#137 Ignore / passthrough specified key combinations

[Jari Pennanen]

Ignore / passthrough specified key combinations. E.g. one could allow only alt+ctrl-left, alt+ctrl-right, Win+1, Win+2 key combinations to be passedthrough allowing (in most cases) switch virtual desktop, but not alt+tab. Currently one cannot configure which keys are passedthrough, the -K switch is next to useless in this matter.

This fix would help my problem. (rdesktop 1.7.1 MacOS 10.6.8)

Have been having trouble with the "stuck windows key" problem. For some reason, the "windows" keypress is interpreted as a toggle rather than a modifier. (Switching off all keyboard "easy access helpers" on the server didn't fix it.) So if I use "command-Q" to quit a fullscreen session, it is captured by the server as a windows key toggle. This is invisible until I use the virtual keyboard to see what is happening, but causes erratic behaviour as the various "windows" key options are apparently randomly activated while typing.

I simply want to stop passthrough of the "windows key". Documentation in rdesktop-source/keymaps/modifiers tells me this is hard coded - and I could fudge it in xkeymap.c. It would be easy to fix and probably more generally useful if this was simply a keymap modifier file line mapping a key to <null>.</null>
