control^r in bash - literally 10x faster to type things which (ideally) makes 10x more productive :)

control^r is reverse search in the command history (for UI people out there).



If you like ctrl^r, you'll _love_ https://github.com/junegunn/fzf


If you like that you should try the fish Shell. Not great for automation but amazing for general use.


It's also Undo in Vim. Cheers!
