Replying to [comment:13 bonefish]:
> Physical key codes are mapped to "virtual" key codes or, as I would name
them in Haiku's case, key roles. E.g. your BView::KeyDown() gets a
`B_COMMAND_KEY` regardless of whether the key you pressed on your keyboard
is actually labeled "Command" or not.
Well, other than making a different keymap for B_OPTION_KEY on Mac
keyboards vs. PC keyboard that is exactly what I am doing. I look at the
virtual keycode and return a bitmap corresponding to it. However, I don't
see how this allows me to localize the bitmap unless I also know the
locale. Maybe there is a function in the Locale kit I could call to get
that information? Although I suppose the correspondence is not 1:1.

key code -> virtual key code -> key role (*) -- it is not helpful (and
even problematic in case of multiple-to-one mapping) to display the actual
legends in KeyMap and use them in menus.
It might be helpful to have a level where you specify your Locale and
Keyboard type, and then build virtual codes on top of that. German -> Mac
-> B_COMMAND_KEY vs. German -> PC -> B_COMMAND_KEY. This would eliminate
one level of keymap indirection. Right now there are a bunch of (Mac)
versions of the keymaps defined in the same locale that could be
eliminated. I don't know, maybe that is overkill.
