Prevent Panel Close w [Cmd]+[W] or [Ctrl]+[W]

When searching for a snippet in many files (e.g., search for the string `<img`), I go back & forth between editor and Find panel.

When I'm done editing that file, I may type [Cmd]+[W] (Command+W on Mac) or [Ctrl]+[W] (Control+W on everything else), frequently, I don't realize that I've switched back to the Find panel, and it closes.

As a result, I now have to re-do my search, and then figure out where I was in the search. If I have 30+ files with `<img` in it, and I'm on the 27 file, I have to remember that I was on file #27, plus identify which line.

Is there a way to tell PhpStorm not to close panels with the Cmd+W?

Thanks!
