* The Ctrl key works like a qualifier for special actions:
24
* Ctrl-Tab = suspend DGA mode (TODO)
25
* Ctrl-Esc = emergency quit
26
* Ctrl-F1 = mount floppy
27
* Ctrl-F5 = grab mouse (in windowed mode)
30
* - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux
31
* - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)
32
* - Mouse acceleration, there is no API in SDL yet for that
33
* - Force relative mode in Grab mode even if SDL provides absolute coordinates?
35
* - Gamma tables support is likely to be broken here
36
* - Events processing is bound to the general emulation thread as SDL requires
37
* to PumpEvents() within the same thread as the one that called SetVideoMode().
38
* Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
39
* - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
40
* - Backport hw cursor acceleration to Basilisk II?
