Description of the Issue

After a search or when press F7 the search results window is opened. It would be nice to close it again with F7. Maybe an option to allow this toggle can be added. At the moment I use a Autohotkey script for this, but it would be nice if this is integrated already

Expected Behavior

Press F7 toggle the search window. If shown, then close it. If closed, then open it.

Actual Behavior

F7 only show the window. When it is already there, nothing happened.
