Advanced Code Editor Redo

I’ve figured out how to access undo (control + Z) but I’m stumped on how to redo. If I can figure this one little thing out I can use this for all my theme editing. I’ve got several sites on goDaddy and that doesn’t allow ftp remote editors, so my old standby is dead in the water unless I use bitwise. That and the Ultimate editor in sftp mode eat my stylesheet intermittently, wipes it clean, at least on goDaddy.

If I can figure out this one little thing I’ll be home free.
