when I customize keyboard accelarators I want to be able to use shift, ctrl, or alt plus a single key. I can then easily link Revit to Voice control software, fingerpad or multi button mouse to do any command I like..... at the moment it appears many bits of alternative input hardware and software dont like to assign say "WA" to a button, rather something like "Shift+W". Revit is very restrictive in this respect at the moment, I have used many other bits of software that I have customised keyboard input and Revit is the first to not let me use these buttons.
