It's trivial to check what key was pressed on win32 without reguard to
"system functions" (such as copy/paste).  Use DirectInput.  This works on
win98 fine, and probably 95 as well.  However I don't know really anything
about how the cross-platform stuff in blender is done, so no idea how
difficult that would be.

sirdude kicked me in the right direction. Thanks! There is a way how to
intecept raw codes. But unfortunately only NT4 and above.... I guess
there are still too much win9x users. (no idea how a current blender
performs on a win9x oven).. And hooking raw codes is somewhat an
overkill for just one hotkey. So far this is one exception to the usual
event handling on windows.

Changing the hotkey is not my problem. Guess I could solve the problem
with a lowlevel hook... This would not affect Blender code, just Win32
GHOST. But this is a bigger change in GHOST and so I prefer to
investigate further and then report again. stay tuned.

Will ask some Win32 guru as soon as possible.
