Close side panel with keystroke or toolbar button

[davidhelp]

I have xyplorer open and see a side panel column on the left with the folder tree and the other column shows the files.

Question: Is there a way to close and re-open the folder tree with a keystroke or adding a button on the toolbar?

Thanks! I added the toolbar button.

Or right-click the status bar and enable swipe. It's cooler than a button.
