If you're sending KEY_SLASH for something that is not /, then that
should get fixed.

Can you explain what they do?  If they're not boolean (up or down), but
instead analogue, it sounds like they need to be valuators rather than
keys.

If they're sliders, then they should be valuators (arbitrary values),
rather than keys (boolean).

These could be slightly more generic, but the comments are _extremely_
OLPC-specific.

XF86XK_Back, XF86XK_Forward?  Or tab and shift-tab?
