Keyboard-only way to display clipboard history filters

Is there a way of triggering the context/filters menu for a particular in the Clipboard History Switcher using the keyboard only?

I'd like to be able to trigger the CHS, use the up/down arrows to select a clipboard item, press another key (right arrow, say) to activate the context/filters menu, use the up/down arrows to find the filter, then press Enter to run the filter. That would make it really quick to be able to "walk" around the tree of items and run filters without taking my hands off the keyboard.

I've tried a few workarounds, but they're unreliable - particularly as right-clicking on an item in the CHW menu ignores whichever item has been selected by the cursor keys.

If this isn't currently easily possible, could keyboard shortcuts for the CHS be a feature request?

Thanks,
Steve
