Is there a keyboard shortcut that achieves the exact same effect as calling Util.ClearResults()?

My program has been running for some time, and now the results pane shows at the bottom. I need to clear the results pane (just like Util.ClearResults() does) but without restarting
my running program.

If no such shortcut exists, would it be possible to add a "Clear Results" option to the dropdown menu on the left side of the Results pane?
