copy clock to clipboard from midi msg?

Is there a way to copy the main clock value in the editor window to the clipboard from a midi event, like the right-button popup menu for the clock does?

I’ve created a small midi device .map file, linking the CC-type messages from the buttons on my midi foot controller to a couple of functions/actions. Buttons for Play, Pause and Nudge-playhead-back function as expected. But I can’t find the function/action name in the .menu or .keys config files to use for copying the clock value to the (linux) clipboard.

(Using Ardour 5.5.0 on linux Ubuntu Studio.)

There is no such function.
