[winswitch] Specifying xmodmap settings (in a file)

[Alexey Loginov]

Okay, thanks for clarifying things!

I'm still a bit confused by the fact that my problem is very similar
to what was discussed in xpra.org/trac/ticket/50 (it talks about a
hack to wrap modifier setting in clear/add context).  There, it was
noted that xpra.org/trac/changeset/325 provides a better fix (reading
actual "xmodmap -pm" settings instead of hardcoding modifier
settings).

All I really care about is the use of the Mac Alt keys (just the left
one would be good enough) as Meta.  The clear/keycode/add sequence is
simply following the standard incantation that's recommended in
various xmodmap discussions and man pages.

Perhaps, I'll try the xpra/xposix/gui.py patch from
xpra.org/trac/ticket/50 (with appropriate modifier changes) to see if
that's enough.

Cheers,
-Alexey
