Definitions
|
|
|
|
c The literal character c.
|
|
|
|
C A single (required) character.
|
|
|
|
Ps A single (usually optional) numeric parameter, composed of one of
|
|
more digits.
|
|
|
|
Pm A multiple numeric parameter composed of any number of single
|
|
numeric parameters, separated by ; character(s). Individual val-
|
|
ues for the parameters are listed with Ps .
|
|
|
|
Pt A text parameter composed of printable characters.
|
|
|
|
C1 (8-Bit) Control Characters
|
|
|
|
The xterm program recognizes both 8-bit and 7-bit control characters.
|
|
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.
|
|
The following pairs of 7-bit and 8-bit control characters are equiva-
|
|
lent:
|
|
|
|
ESC D
|
|
Index (IND is 0x84)
|
|
ESC E
|
|
Next Line (NEL is 0x85)
|
|
ESC H
|
|
Tab Set (HTS is 0x88)
|
|
ESC M
|
|
Reverse Index (RI is 0x8d)
|
|
ESC N
|
|
Single Shift Select of G2 Character Set (SS2 is 0x8e): affects
|
|
next character only
|
|
ESC O
|
|
Single Shift Select of G3 Character Set (SS3 is 0x8f): affects
|
|
next character only
|
|
ESC P
|
|
Device Control String (DCS is 0x90)
|
|
ESC V
|
|
Start of Guarded Area (SPA is 0x96)
|
|
ESC W
|
|
End of Guarded Area (EPA is 0x97)
|
|
ESC X
|
|
Start of String (SOS is 0x98)
|
|
ESC Z
|
|
Return Terminal ID (DECID is 0x9a). Obsolete form of CSI c (DA).
|
|
ESC [
|
|
Control Sequence Introducer (CSI is 0x9b)
|
|
ESC \
|
|
String Terminator (ST is 0x9c)
|
|
ESC ]
|
|
Operating System Command (OSC is 0x9d)
|
|
ESC ^
|
|
Privacy Message (PM is 0x9e)
|
|
ESC _
|
|
Application Program Command (APC is 0x9f)
|
|
|
|
These control characters are used in the vtXXX emulation.
|
|
|
|
VT100 Mode
|
|
Most of these control sequences are standard VT102 control sequences,
|
|
but there is support for later DEC VT terminals (i.e., VT220, VT320,
|
|
VT420), as well as ISO 6429 and aixterm color controls. The only VT102
|
|
features not supported is auto-repeat, since the only way X provides for
|
|
this will affect all windows. There are additional control sequences to
|
|
provide xterm-dependent functions, such as the scrollbar or window size.
|
|
Where the function is specified by DEC or ISO 6429, the code assigned to
|
|
it is given in parentheses. The escape codes to designate and invoke
|
|
character sets are specified by ISO 2022; see that document for a dis-
|
|
cussion of character sets.
|
|
|
|
Single-character functions
|
|
BEL Bell (Ctrl-G)
|
|
BS Backspace (Ctrl-H)
|
|
CR Carriage Return (Ctrl-M)
|
|
ENQ Return Terminal Status (Ctrl-E). Default response is an empty
|
|
string, but may be overridden by a resource answerbackString.
|
|

|
|
LF Line Feed or New Line (NL) (Ctrl-J)

|
|
VT Vertical Tab (Ctrl-K) same as LF
|
|
SI Shift In (Ctrl-O) -> Switch to Standard Character Set: invokes
|
|
the G0 character set (the default).
|
|
|
|
Controls beginning with ESC (other than those where ESC is part of a
|
|
7-bit equivalent to 8-bit C1 controls), ordered by the final charac-
|
|
ter(s).
|
|
ESC SP F 7-bit controls (S7C1T).
|
|

Application Program-Control functions
|
|
APC Pt ST xterm implements no APC functions; Pt is ignored. Pt need
|
|
not be printable characters.
|
|
|
|
Device-Control functions
|
|
DCS Ps; Ps| Pt ST
|
|
User-Defined Keys (DECUDK). The first parameter:
|
|
Ps = 0 -> Clear all UDK definitions before starting
|
|
(default)
|
|
Ps = 1 -> Erase Below (default)
|
|
The second parameter:
|
|
Ps = 0 -> Lock the keys (default)
|
|
Ps = 1 -> Do not lock.
|
|
The third parameter is a ';'-separated list of strings denot-
|
|
ing the key-code separated by a '/' from the hex-encoded key
|
|
value. The key codes correspond to the DEC function-key codes
|
|
(e.g., F6=17).
|
|
DCS $ q Pt ST
|
|
Request Status String (DECRQSS). The string following the "q"
|
|
is one of the following:
|
|
" q -> DECSCA
|
|
" p -> DECSCL
|
|
r -> DECSTBM
|
|
m -> SGR
|
|
xterm responds with DCS 1 $ r Pt ST for valid requests,
|
|
replacing the Pt with the corresponding CSI string, or DCS 0 $
|
|
r Pt ST for invalid requests.
|
|
DCS + q Pt ST
|
|
Request Termcap/Terminfo String (xterm, experimental). The
|
|
string following the "q" is a list of names encoded in hex-
|
|
adecimal (2 digits per character) separated by ; which corre-
|
|
spond to termcap or terminfo key names.
|
|
xterm responds with DCS 1 + r Pt ST for valid requests, adding
|
|
to Pt an = , and the value of the corresponding string that
|
|
xterm would send, or DCS 0 + r Pt ST for invalid requests.
|
|
The strings are encoded in hexadecimal (2 digits per charac-
|
|
ter).

-> CSI ? 6 c (``VT102'')
|
|
-> CSI ? 6 0 ; 1 ; 2 ; 6 ; 8 ; 9 ; 1 5 ; c (``VT220'')
|
|
The VT100-style response parameters do not mean anything by
|
|
themselves. VT220 parameters do, telling the host what fea-
|
|
tures the terminal supports:
|
|
-> 1 132-columns
|
|
-> 2 Printer
|
|
-> 6 Selective erase
|
|

|
|
-> 1 5 Technical characters
|
|

|
|
-> 2 9 ANSI text locator (i.e., DEC Locator mode)
|
|
CSI > Ps c
|
|
Send Device Attributes (Secondary DA)
|
|
Ps = 0 or omitted -> request the terminal's identification
|
|
code. The response depends on the decTerminalID resource set-
|
|
ting. It should apply only to VT220 and up, but xterm extends
|
|
this to VT100.

|
and Pv is the firmware version (for xterm, this was originally
|
|
the XFree86 patch number, starting with 95). In a DEC termi-
|
|
nal, Pc indicates the ROM cartridge registration number and is
|
|
always zero.

If 16-color support is compiled, the following apply. Assume
|
|
that xterm's resources are set so that the ISO color codes are
|
|
the first 8 of a set of 16. Then the aixterm colors are the
|
|
bright versions of the ISO colors:

supports the following, from rxvt:
|
|
Ps = 1 0 0 -> Set foreground and background color to
|
|

|
|
|
|
If 88- or 256-color support is compiled, the following apply.

|
|
Ps = 4 8 ; 5 ; Ps -> Set background color to the second Ps
|
|
|

|
Set or reset resource-values used by xterm to decide whether
|
|
to construct escape sequences holding information about the
|
|
modifiers pressed with a given key. The first parameter iden-
|
|
tifies the resource to set/reset. The second parameter is the
|
|
value to assign to the resource. If the second parameter is
|
|
omitted, the resource is reset to its initial value.
|

CSI > Ps n
|
|
Disable modifiers which may be enabled via the CSI > Ps; Ps m

cannot be set with the other sequence. The parameter identi-
|
|
fies the resource to be disabled:
|
|
-> 1 modifyCursorKeys
|
|
-> 2 modifyFunctionKeys
|
|
-> 4 modifyOtherKeys If the parameter is omitted, modify-
|
|
FunctionKeys is disabled. When modifyFunctionKeys is dis-
|
|
abled, xterm uses the modifier keys to make an extended
|
|
sequence of functions rather than adding a parameter to each
|
|
function key to denote the modifiers.
|
|

|
Enable Filter Rectangle (DECEFR)
|
|
Parameters are [top;left;bottom;right].
|
|
Defines the coordinates of a filter rectangle and activates
|
|
it. Anytime the locator is detected outside of the filter
|
|
rectangle, an outside rectangle event is generated and the
|
|
rectangle is disabled. Filter rectangles are always treated
|
|
as "one-shot" events. Any parameters that are omitted default
|
|
to the current locator position. If all parameters are omit-
|
|
ted, any locator motion will be reported. DECELR always can-
|
|
cels any prevous rectangle definition.
|
|
CSI Ps x Request Terminal Parameters (DECREQTPARM)
|
|
if Ps is a "0" (default) or "1", and xterm is emulating VT100,
|
|
the control sequence elicits a response of the same form whose

|
|
Ps = 0 , 1 or omitted -> transmit a single DECLRP locator
|
|
report
|
|
|
|
If Locator Reporting has been enabled by a DECELR, xterm will

respond with a DECLRP Locator Report. This report is also
|
|
generated on button up and down events if they have been
|
|
enabled with a DECSLE, or when the locator is detected outside
|
|
of a filter rectangle, if filter rectangles have been enabled
|
|
with a DECEFR.
|
|
|
|
-> CSI Pe ; Pb ; Pr ; Pc ; Pp & w
|
|
|
|
Parameters are [event;button;row;column;page].
|
|

|
|
Pb & 1 -> right button down
|
|
Pb & 2 -> middle button down
|
|
Pb & 4 -> left button down
|
|
Pb & 8 -> M4 button down
|
|
``row'' and ``column'' parameters are the coordinates of the
|
|
locator position in the xterm window, encoded as ASCII deci-
|
|
mal.
|
|
The ``page'' parameter is not used by xterm, and will be omit-
|
|
ted.

Operating System Controls
|
|
OSC Ps ; Pt ST
|
|
OSC Ps ; Pt BEL
|
|
Set Text Parameters. For colors and font, if Pt is a "?", the
|
|
control sequence elicits a response which consists of the con-
|
|
trol sequence which would set the corresponding value. The
|
|
dtterm control sequences allow you to determine the icon name
|
|
and window title.
|
|
Ps = 0 -> Change Icon Name and Window Title to Pt
|
|
Ps = 1 -> Change Icon Name to Pt
|
|
Ps = 2 -> Change Window Title to Pt
|
|
Ps = 3 -> Set X property on top-level window. Pt should be
|
|
in the form "prop=value", or just "prop" to delete the prop-
|
|
erty
|
|
Ps = 4 ; c ; spec -> Change Color Number c to the color
|
|
specified by spec, i.e., a name or RGB specification as per
|
|
XParseColor. Any number of c name pairs may be given. The
|
|
color numbers correspond to the ANSI colors 0-7, their bright
|
|
versions 8-15, and if supported, the remainder of the 88-color
|
|
or 256-color table.
|
|
|
|
If a "?" is given rather than a name or RGB specification,
|
|
xterm replies with a control sequence of the same form which
|
|
can be used to set the corresponding color. Because more than
|
|
one pair of color number and specification can be given in one
|
|
control sequence, xterm can make more than one reply.
|
|
|
|
The 8 colors which may be set using 1 0 through 1 7 are
|
|
denoted dynamic colors, since the corresponding control
|
|
sequences were the first means for setting xterm's colors
|
|
dynamically, i.e., after it was started. They are not the
|
|
same as the ANSI colors. One or more parameters is expected
|
|
for Pt. Each successive parameter changes the next color in
|
|
the list. The value of Ps tells the starting point in the
|
|
list. The colors are specified by name or RGB specification
|
|
as per XParseColor.
|
|
|
|
If a "?" is given rather than a name or RGB specification,
|
|
xterm replies with a control sequence of the same form which
|
|
can be used to set the corresponding dynamic color. Because
|
|
more than one pair of color number and specification can be
|
|
given in one control sequence, xterm can make more than one
|
|
reply.
|
|
|
|
Ps = 1 0 -> Change VT100 text foreground color to Pt
|
|
Ps = 1 1 -> Change VT100 text background color to Pt
|
|
Ps = 1 2 -> Change text cursor color to Pt
|
|
Ps = 1 3 -> Change mouse foreground color to Pt
|
|
Ps = 1 4 -> Change mouse background color to Pt

|
|
Ps = 1 6 -> Change Tektronix background color to Pt
|
|

|
|
|
|
Ps = 4 6 -> Change Log File to Pt (normally disabled by a
|
|
compile-time option)
|
|
|
|
Ps = 5 0 -> Set Font to Pt If Pt begins with a "#", index
|
|
in the font menu, relative (if the next character is a plus or
|
|
minus sign) or absolute. A number is expected but not
|
|
required after the sign (the default is the current entry for
|
|
relative, zero for absolute indexing).
|
|
|
|
Ps = 5 1 (reserved for Emacs shell)
|
|
|
|
Ps = 5 2 -> Manipulate Selection Data. These controls may
|
|
be disabled using the allowWindowOps resource. The parameter
|
|
Pt is parsed as
|
|
Pc; Pd
|
|
The first, Pc, may contain any character from the set c p s
|
|
0 1 2 3 4 5 6 7 . It is used to construct a list of
|
|
selection parameters for clipboard, primary, select, or cut
|
|
buffers 0 through 8 respectively, in the order given. If the
|
|
parameter is empty, xterm uses s 0 , to specify the config-
|
|
urable primary/clipboard selection and cut buffer 0.
|
|
The second parameter, Pd, gives the selection data. Normally
|
|
this is a string encoded in base64. The data becomes the new
|
|
selection, which is then available for pasting by other appli-
|
|
cations.
|
|
If the second parameter is a ? , xterm replies to the host
|
|
with the selection data encoded using the same protocol.

|
|
|
|
Alt and Meta Keys
|
|
Many keyboards have keys labeled "Alt". Few have keys labeled "Meta".
|
|
However, xterm's default translations use the Meta modifier. Common
|
|
keyboard configurations assign the Meta modifier to an "Alt" key. By
|
|
using xmodmap one may have the modifier assigned to a different key, and
|
|
have "real" alt and meta keys. Here is an example:
|
|
|
|
! put meta on mod3 to distinguish it from alt
|
|
keycode 64 = Alt_L
|
|
clear mod1
|
|
add mod1 = Alt_L
|
|
keycode 115 = Meta_L
|
|
clear mod3
|
|
add mod3 = Meta_L
|
|
|
|
The metaSendsEscape resource (and altSendsEscape if altIsNotMeta is set)
|
|
can be used to control the way the Meta modifier applies to ordinary
|
|
keys unless the modifyOtherKeys resource is set:
|
|
- prefix a key with the ESC character.
|
|
- shift the key from codes 0-127 to 128-255 by adding 128.
|
|
The table shows the result for a given character "x" with modifiers
|
|
according to the default translations with the resources set on or off.
|
|
This assumes altIsNotMeta is set:
|
|
|
|
-----------------------------------------------------------

PC-Style Function Keys
|
|
If xterm does minimal translation of the function keys, it usually does
|
|
this with a PC-style keyboard, so PC-style function keys result. Sun
|
|
keyboards are similar to PC keyboards. Both have cursor and scrolling
|
|
operations printed on the keypad, which duplicate the smaller cursor and
|
|
scrolling keypads.
|
|
X does not predefine NumLock (used for VT220 keyboards) or Alt (used as
|
|
an extension for the Sun/PC keyboards) as modifiers. These keys are
|
|
recognized as modifiers when enabled by the numLock resource, or by the
|
|
DECSET 1 0 3 5 control sequence.
|
|
The cursor keys transmit the following escape sequences depending on the
|
|
mode specified via the DECCKM escape sequence.

|
The home- and end-keys (unlike PageUp and other keys also on the 6-key
|
|
editing keypad) are considered "cursor keys" by xterm. Their mode is
|
|
also controlled by the DECCKM escape sequence:

The application keypad transmits the following escape sequences depend-
|
|
ing on the mode specified via the DECPNM and DECPAM escape sequences.
|
|
Use the NumLock key to override the application mode.
|
|
Not all keys are present on the Sun/PC keypad (e.g., PF1, Tab), but are
|
|
supported by the program.

Older versions of xterm implement different escape sequences for F1
|
|
through F4. These can be activated by setting the oldXtermFKeys
|
|
resource. However, since they do not correspond to any hardware termi-
|
|
nal, they have been deprecated. (The DEC VT220 reserves F1 through F5
|
|
for local functions such as Setup).

In normal mode, i.e., a Sun/PC keyboard when the sunKeyboard resource is
|
|
false, xterm recognizes function key modifiers which are parameters
|
|
appended before the final character of the control sequence.

---------------------------------
|
|
|
|
For example, shift-F5 would be sent as CSI 1 5 ; 2 ~
|
|
If the alwaysUseMods resource is set, the Meta modifier also is recog-
|
|
nized, making parameters 9 through 16.
|
|
|
|
VT220-Style Function Keys
|
|
However, xterm is most useful as a DEC VT102 or VT220 emulator. Set the
|
|
sunKeyboard resource to true to force a Sun/PC keyboard to act like a
|
|
VT220 keyboard.
|
|
|
|
The VT102/VT220 application keypad transmits unique escape sequences in
|
|
application mode, which are distinct from the cursor and scrolling key-

The VT220 provides a 6-key editing keypad, which is analogous to that on
|
|
the PC keyboard. It is not affected by DECCKM or DECPNM/DECPAM:

VT52-Style Function Keys

A VT52 does not have function keys, but it does have a numeric keypad
|
|
and cursor keys. They differ from the other emulations by the prefix.

Also, the cursor keys do not change:

Sun-Style Function Keys
|
|
The xterm program provides support for Sun keyboards more directly, by a
|
|
menu toggle that causes it to send Sun-style function key codes rather
|
|
than VT220. Note, however, that the sun and VT100 emulations are not
|
|
really compatible. For example, their wrap-margin behavior differs.
|
|
Only function keys are altered; keypad and cursor keys are the same.
|
|
The emulation responds identically. See the xterm-sun terminfo entry
|
|
for details.
|
|
|
|
HP-Style Function Keys
|
|
Similarly, xterm can be compiled to support HP keyboards. See the
|
|
xterm-hp terminfo entry for details.
|
|
|
|
The Alternate Screen Buffer
|
|
Xterm maintains two screen buffers. The normal screen buffer allows you
|
|
to scroll back to view saved lines of output up to the maximum set by
|
|
the saveLines resource. The alternate screen buffer is exactly as large
|
|
as the display, contains no additional saved lines. When the alternate
|
|
screen buffer is active, you cannot scroll back to view saved lines.
|
|
Xterm provides control sequences and menu entries for switching between
|
|
the two.
|
|
|
|
Most full-screen applications use terminfo or termcap to obtain strings
|
|
used to start/stop full-screen mode, i.e., smcup and rmcup for terminfo,
|
|
or the corresponding ti and te for termcap. The titeInhibit resource
|
|
removes the ti and te strings from the TERMCAP string which is set in
|
|
the environment for some platforms. That is not done when xterm is
|
|
built with terminfo libraries because terminfo does not provide the
|
|
whole text of the termcap data in one piece. It would not work for ter-
|
|
minfo anyway, since terminfo data is not passed in environment vari-
|
|
ables; setting an environment variable in this manner would have no
|
|
effect on the application's ability to switch between normal and alter-
|
|
nate screen buffers. Instead, the newer private mode controls (such as
|
|
1 0 4 9 ) for switching between normal and alternate screen buffers sim-
|
|
ply disable the switching. They add other features such as clearing the
|
|
display for the same reason: to make the details of switching indepen-
|
|
dent of the application that requests the switch.
|
|
|
|
Bracketed Paste Mode
|
|
When bracketed paste mode is set, pasted text is bracketed with control
|
|
sequences so that the program can differentiate pasted text from typed-
|
|
in text. When bracketed paste mode is set, the program will receive:
|
|
ESC [ 200 ~, followed by the pasted text, followed by ESC [ 201 ~.
|
|
|
|
Mouse Tracking
|
|
The VT widget can be set to send the mouse position and other informa-
|
|
tion on button presses. These modes are typically used by editors and
|
|
other full-screen applications that want to make use of the mouse.
|
|
|
|
There are six mutually exclusive modes. One is DEC Locator mode,
|
|
enabled by the DECELR CSI Ps ; Ps ' z control sequence, and is not
|
|
described here (control sequences are summarized above). The remaining
|
|
five modes are each enabled (or disabled) by a different parameter in
|
|
DECSET CSI ? Pm h or DECRST CSI ? Pm l control sequence.
|
|
|
|
Manifest constants for the parameter values are defined in xcharmouse.h
|
|
as follows:
|
|
|
|
#define SET_X10_MOUSE 9
|
|
#define SET_VT200_MOUSE 1000
|
|
#define SET_VT200_HIGHLIGHT_MOUSE 1001
|
|
#define SET_BTN_EVENT_MOUSE 1002
|
|
#define SET_ANY_EVENT_MOUSE 1003
|
|
|
|
#define SET_FOCUS_EVENT_MOUSE 1004
|
|
|
|
The motion reporting modes are strictly xterm extensions, and are not
|
|
part of any standard, though they are analogous to the DEC VT200 DECELR
|
|
locator reports.
|
|
|
|
Parameters (such as pointer position and button number) for all mouse
|
|
tracking escape sequences generated by xterm encode numeric parameters
|
|
in a single character as value+32. For example, ! specifies the value
|
|
1. The upper left character position on the terminal is denoted as 1,1.
|
|
|
|
X10 compatibility mode sends an escape sequence only on button press,
|
|
encoding the location and the mouse button pressed. It is enabled by
|
|
specifying parameter 9 to DECSET. On button press, xterm sends CSI M
|
|
CbCxCy (6 characters). Cb is button-1. Cx and Cy are the x and y coor-
|
|
dinates of the mouse when the button was pressed.
|
|
|
|
Normal tracking mode sends an escape sequence on both button press and
|
|
release. Modifier key (shift, ctrl, meta) information is also sent. It
|
|
is enabled by specifying parameter 1000 to DECSET. On button press or
|
|
release, xterm sends CSI M CbCxCy. The low two bits of Cb encode button
|
|
information: 0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
|
|
The next three bits encode the modifiers which were down when the button
|
|
was pressed and are added together: 4=Shift, 8=Meta, 16=Control. Note
|
|
however that the shift and control bits are normally unavailable because
|
|
xterm uses the control modifier with mouse for popup menus, and the
|
|
shift modifier is used in the default translations for button events.
|
|
The Meta modifier recognized by xterm is the mod1 mask, and is not nec-
|
|
essarily the "Meta" key (see xmodmap). Cx and Cy are the x and y coor-
|
|
dinates of the mouse event, encoded as in X10 mode.
|
|
|
|
Wheel mice may return buttons 4 and 5. Those buttons are represented by
|
|
the same event codes as buttons 1 and 2 respectively, except that 64 is
|
|
added to the event code. Release events for the wheel buttons are not
|
|
reported.
|
|
|
|
Mouse highlight tracking notifies a program of a button press, receives
|
|
a range of lines from the program, highlights the region covered by the
|
|
mouse within that range until button release, and then sends the program
|
|
the release coordinates. It is enabled by specifying parameter 1001 to
|
|
DECSET. Highlighting is performed only for button 1, though other but-
|
|
ton events can be received. Warning: use of this mode requires a coop-
|
|
erating program or it will hang xterm. On button press, the same infor-
|
|
mation as for normal tracking is generated; xterm then waits for the
|
|
program to send mouse tracking information. All X events are ignored
|
|
until the proper escape sequence is received from the pty: CSI Ps ; Ps ;
|
|
Ps ; Ps ; Ps T . The parameters are func, startx, starty, firstrow, and
|
|
lastrow. func is non-zero to initiate highlight tracking and zero to
|
|
abort. startx and starty give the starting x and y location for the
|
|
highlighted region. The ending location tracks the mouse, but will
|
|
never be above row firstrow and will always be above row lastrow. (The
|
|
top of the screen is row 1.) When the button is released, xterm reports
|
|
the ending position one of two ways: if the start and end coordinates
|
|
are valid text locations: CSI t CxCy. If either coordinate is past the
|
|
end of the line: CSI T CxCyCxCyCxCy. The parameters are startx, starty,
|
|
endx, endy, mousex, and mousey. startx, starty, endx, and endy give the
|
|
starting and ending character positions of the region. mousex and
|
|
mousey give the location of the mouse at button up, which may not be
|
|
over a character.
|
|
|
|
Button-event tracking is essentially the same as normal tracking, but
|
|
xterm also reports button-motion events. Motion events are reported
|
|
only if the mouse pointer has moved to a different character cell. It
|
|
is enabled by specifying parameter 1002 to DECSET. On button press or
|
|
release, xterm sends the same codes used by normal tracking mode. On
|
|
button-motion events, xterm adds 32 to the event code (the third charac-
|
|
ter, Cb). The other bits of the event code specify button and modifier
|
|
keys as in normal mode. For example, motion into cell x,y with button 1
|
|
down is reported as CSI M @ CxCy. ( @ = 32 + 0 (button 1) + 32 (motion
|
|
indicator) ). Similarly, motion with button 3 down is reported as CSI M
|
|
B CxCy. ( B = 32 + 2 (button 3) + 32 (motion indicator) ).
|
|
|
|
Any-event mode is the same as button-event mode, except that all motion
|
|
events are reported, even if no mouse button is down. It is enabled by
|
|
specifying 1003 to DECSET.
|
|
|
|
FocusIn/FocusOut can be combined with any of the mouse events since it
|
|
uses a different protocol. When set, it causes xterm to send CSI I
|
|
when the terminal gains focus, and CSI O when it loses focus.
|
