In bash, I use the history-search-forward and history-search-backward feature to allow me to type in a few characters of the command I want to run, then press up arrow to cycle
Reverse search feature is not there in Chrome developer tools. I have logged a request for the reverse search feature. Please star the same.

I use Snippets (Chrome Developer Tools: What is Snippets Support?) for keeping track of all my commands.
