I use Ctrl+R all the time, but I often end up going past the command I'm after as I'm pressing it so quickly.
To forward search, Ctrl+S can be used provided it's not used the terminal first (konsole in my case, in which
stty -ixon in
~/.bashrc fixes it).
However, I have to press it twice: once it seems to enter
i-search after being in
reverse-i-search mode and a second time to actually step backwards.
Is there a way to remove the need for pressing the shortcut twice?
