Adding keyboard shortcuts to rich text editor

[chillibear]

Hello all. Is it possible to easily add shortcut keys to the buttons in the rich text editor? Obviously some have codes already (Bold, Italic, etc) however quite a few of the users on one of my boards would like to be able to toggle the BB Code editing mode from the keyboard directly and I was wondering how easy it might be to add a shortcut key? Thank you.
