Yes, very odd. In fact, it writes "Pause" where it should say
"NumLock". The reason is in windows itself.. it returns "Pause" for
the scancode of the numlock key. It can be easily fixed with a special
case (so KEY_PAUSE and KEY_NUMLOCK won't be localized). Quite probably
I'm somehow doing something wrong here:
if (GetKeyNameText(reverse_mapping[scancode] << 16, str, sizeof str))
It returns 0 for the pause key (so simple Allegro's "PAUSE" is used as
text, but it returns != 0 for the numlock key, and writes the string
"PAUSE" into str. MSDN isn't really helpful here as well:

Which one? The key labelled VK_RMENU here is always reported together
with the control flag (by windows), the key VK_LMENU is the left alt
key and reported as only the alt flag. I don't think there's much
point special casing this and "fixing" what windows reports..

They should.

What different values do they give?

What should be different?
