I would like to have a good guide to the common Control key combinations in use in bash (and similar) shells and the combinations used by common programs in use in those shells.
My particular motivation is to be able to run GNU screen on one computer, ssh to a second computer and use screen and irssi on that computer. So I need to use something other than Ctrl-A to control one of the screen sessions. So I need to know what are Control key combinations are safe to use.
But I imagine this list would be useful for others who want to bind custom actions to Control key combinations.
I reckon we'd be best to group the Control key combinations by application (eg. bash itself, screen, vim, emacs), to make it easy to spot the applications you use or can ignore. So please one application per answer - hope that works.
