These are ways to repeat interactive commands or shorten the number of keys it takes to accomplish things. These features make one more efficient, but also can avoid disabilities like RSI.
- RepeatLastCommand - Emacs can display the previous command in Emacs Lisp and prompt you to re-execute it.
- KeyboardMacros - Encapsulate a number of keyboard sequences into a macro and repeat it.
- RepeatingCommandsLikeVi - If you long for the “.” command.
- RepetitionDetection - Let Emacs tell you when you’re repeating yourself.
- UniversalArgument - Provide an argument to any command, often to repeat it.
- DoReMi – Run commands repetitively or iteratively, using the arrow keys or the mouse wheel to repeat or iterate.
- Repeatable – Repeat commands bound to complex key sequences by only pressing the last key again.
- RepeatKeyDifferentBehaviors – Repeating the same key and getting different behaviors, in a cycle.
