From that perspective, using Ctrl+R and Ctrl+S for reverse-i-search in a shell saves me so much time from writing commands especially big Kubernetes ones.

It's also useful to remove duplicate commands and store infinite history. Add this to ~/.bashrc:
export HISTFILESIZE=
export HISTSIZE=
export HISTCONTROL=ignoredups > big hairy command with --lots --of arguments # foobar
Then you can search for 'foobar' via fzf or whatnot.It's saved me countless hours over the years as it's just so much better than regular CTRL-R. I also find it to work better than fzf.
