Typing numbers will get you into a multiple selection mode, which you
can use (for example) to draw yourself a hand of multiple cards.
+Typing just "1" will let you select the first available card, even if

+someone is holding onto the deck).
Typing a zero will get you into a special selection mode for selecting
the lowermost piece. This can useful to grasp a hand or pickup deck
