Nintendo DS shortcuts should be listed in the shortcuts window
GtkShortcutsWindow doesn't play good with anything dynamic. While it is possible to add a shortcut in runtime, it's complicated and when I tried it, search didn't work, so it probably involves hardcoding the shortcuts in XML.
The current shortcuts are:
- PgUp and PgDn for switching between top and bottom screen in quick switch mode;
- Pressing right analog stick for the same thing;
