I think this was my original idea way back when. A comment from one of the participants supports this interaction pattern. He mentioned that in gaming, he often uses the Spacebar to pickup AND drop things.\r\n\r\nWith an example interaction pattern:\r\n\r\n>user moves focus to balloon with the Tab key and hears \"Play with Balloon, button\".\r\nuser presses Spacebar (or Enter) to play with the Balloon.\r\nNav/interaction cue is read out. \"Use W, A, S...to drag balloon up, left.... Press Spacebar to release.\""}}
