|
* NOTES: |
23 |
|
|
* The Ctrl key works like a qualifier for special actions: |
24 |
|
|
* Ctrl-Tab = suspend DGA mode |
25 |
|
|
* Ctrl-Esc = emergency quit |
26 |
|
|
* Ctrl-F1 = mount floppy |
27 |
|
|
* Ctrl-F5 = grab mouse (in windowed mode) |
28 |
|
|
* |
29 |
|
|
* FIXMEs and TODOs: |
30 |
|
|
* - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?) |
31 |
|
|
* - Mouse acceleration, there is no API in SDL yet for that |
32 |
|
|
* - Force relative mode in Grab mode even if SDL provides absolute coordinates? |
33 |
|
|
* - Fullscreen mode |
34 |
|
|
* - Gamma tables support is likely to be broken here |
