I strongly agree with Gerry's arguments. Here's what I wrote about it

Just make up SDL's own set of codes, and have each backend
implementation map from its OS or hardware dependent scancodes to that
set? If that's not possible on some OSes, they can still fall back to
It's easy to do on Mac OS X. It's already done on DirectX. On X11, it's
a bit more complex - it seems that X-server- and/or hardware-specific
look-up tables would be needed, but this could still be done for the
most common cases (XFree86/Xorg on PC and Mac hardware, at least), with
a graceful fallback to mapping-by-character on other systems.

On what OS and hardware is that? I have never seen a system where the OS
does not need to be told what's printed on your keycaps. Or does your
Dvorak keyboard actually move the keys around compared to the Qwerty
keyboard, instead of just relabeling them? If so, I don't think that's
the norm. My US keyboard has the keys in the same places as my Swiss
German one (mostly), they're just labeled differently.
