Clever control sequence for pre-used console commands

You know how it is, you open a new terminal window assured you know the command you want to use you make a cup of coffee and then you forget the command you where to use. Obviously you need better coffee!

Or you can press the "Control Key + r" and your command prompt is replaced with this

(reverse-i-search)`':

What is so impressive with this control sequence, is that you don't need to remember the whole command and or the command syntax, there is of course a slight draw back, you need to have used the correct command before and the correct spelling at the beginning of the command is most important.

Try the control key command yourself it eases the pressure on the brain stem.
