This is coming from but does not close #7967 Adds a new (currently unused) Menu key bitmap. Instead of having a single AltAsCommandKey() method the menus now show the correct bitmap when you switch between your control, windows/option, and alt/command keys. This is really not flushed out yet since it only works when you switch those keys and not other combinations like say switching the control and caps lock keys but it is a step in the right direction. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43205 a95241bf-73f2-0310-859d-f6bbb57e9c96
