|
|
* broken. Versions of xkbcomp below 1.2.2 had a bug where they
|
|
* would interpret a symbol that couldn't be found in an interpret
|
|
* as Any. So, an XF86LogWindowTree+AnyOfOrNone(All) interp that
|
|
* triggered the PrWins action would make every key without an
|
|
* action trigger PrWins if libX11 didn't yet know about the
|
|
* XF86LogWindowTree keysym. None too useful.
|
|
*
|
|
* We only do this for XFree86 actions, as the current XKB
|
|
* dataset relies on Any+AnyOfOrNone(All) -> SetMods for Ctrl in
|
|
* particular.
|
|
*
|
