Short names of keybindings

[SonOfArn]

This is mainly a cosmetic change, but would it be possible to change the short names for the keybindings? When you bind to a mouse button it say "BUT..." och "sBU..." etc so in my oppinion the important part is left out, namely the button number.

Perhaps something like this could work: "Bt4", "sBt4" etc?

I can look at that -- it does shorten the name of the keys, I thought it did mouse buttons, too, but maybe not.
