[Feature Request] Add ability to clear previous results

When you perform a search, the results show up in the file pane, but there does not appear to be any way to clear the file pane if desired.
Maybe can add a way to clear the results from previous search, without having to perform another search.
Suggesting the following to be added to achieve this
-Context menu item
-Hotkey I was thinking the "Escape" key but depends if the following is decided to be added #126 (closed) which may be a better use for this hotkey?
"Escape" key is tricky in this program because I often find myself hitting it because I am expecting it to work for multiple things, but it does not. Not sure if others do this as well, if so might not be the best hotkey because user might clear search results by accident, often.

Thank You
