How can I program the rc.lua file to enable a keyboard shortcut to move a window from one tag on one screen to a tag that is on a different screen? I know the modkey + shift + [tag number] shortcut, but that moves the window only to a different tag on the same screen.
For example: I want to move a window from the first tag on screen one to the third tag on screen 2 (or at least to the active tag on screen 2).
