Start selection of menu items at index 0

The menu items appear always in the same order. Therefore selecting the
second item (0-based list) appears to be a bit arbitrary, as it is
sometimes the currently focused window, the next window or some other
window.

Not sure about this, maybe the window ordering is wrong because my wm (xmonad) sets them wrong?

If I open a couple of windows, each on a separate workspace, the window/workspace order seems always to be the same, regardless which one was focused last.

Focusing the 2nd element of this list creates additional confusion.
