You can assign your own shortcut key to the internal command cm_MatchSrc - that will copy the tab CONTENT to the other window, but perhaps that is not what you want?
Do you in stead want a NEW tab in the other window with the same content as the current tab? Then place the cursor on a file (not a foder) and press Shift+Ctrl+ArrowUp.
