Run the word under the cursor when Enter is pressed in a header

The workspace and column tags hold nothing but commands, and before they
became texts Enter on one of them ran it: Enter on Newcol made a column.
Since then Enter looked the word up, as it does in a pane's tag, which only
searched for it. It runs it again, and the header lets go of the keyboard
first as a pane tag does.
