A simple key synthesizer using an XSendEvent-ed KeyPress/KeyRelease.
Warning: (u)xterm will ignore key presses generated by XSendEvent, thus
you will not be able to synthesize key presses for such apps. Press
Ctrl+Button1 and hit "Allow SendEvents" to change that for
xterm. Defining the xresource XTerm.*.*.allowSendEvents=true might also
work.
Useful for:
I'm using F2, F3, F4 for ion commands like spawn xterm, run app, or a
lua prompt. I use these function much more often than functions that are
bound by applications to F2, F3, F4.. But I need to access these
function occasionally. Therefor, I use Meta-F2 to synthesize a regular
F2 event. This can be done by
kpress(MOD1.."F2", "WClientWin.synthesize_key(_sub, 'F2')"),
in the binding map for WMPlex.
