@Swehtc - I'm with you! On my RSI friendly keyboard typing Ctrl+Alt+Z is incredibly uncomfortable, and basically requires two hands. THE keyboard shortcut I want all the time can't be that uncomfortable to type!
I have very bad RSI - and many of the default keyboard shortcuts are very uncomfortable to type on my special keyboard.I would argue that customizable keyboard shortcuts is a fundamental accessibility issue too.Would LOVE to see this in Firefox.
