A command of a contextual menu item

[babalooza]

Hi,

is it possible to map a command of a contextual menu item?

I use grouped folders and I want to delete all junk emails from several email addresses in the grouped junk folder with a keyboard shortcut. Right now on my Mac I have to right-click (or control-click) the grouped junk folder and select "delete junk" from the pop up menu. And that's what I want to do with a shortcut.

If that is possible, can I use the keyboard shortcut "option + command + J", because that is the keyboard shortcut in Apple Mail for the same action.

Thanks in advance!
