Feature request description

Sourcegraph search is great, but there is often a long gap between when I search, browse around, and search again on the same page. If I hit "Cmd-F" again, it should rehighlight the search query. Most search shortcuts work this way. For example: Chrome's Cmd-F highlights, and so does its Cmd-L (address bar).

Sourcegraph does highlight if I'm not focused on the search box but I'm requesting Cmd-F to always rehighlight even I'm already focused on the search box.

Is your feature request related to a problem? If so, please describe.

Without this, I'm frequently appending instead of replacing.

I'd like to search multiple times and save some keystrokes and behave idiomatically.
