Currently, suggest shows only when the fileld isn’t empty. It makes discovering all acceptable values harder. Firebug behaviour: http://www.screenr.com/qYs7.

What’s the purpose of the `force` flag in TextPrompt.js? I haven’t yet found a case when it’s defined.
`force` is true only when you press Ctrl + Space. It’s quite hard to discover. Having arrow keys to force showing suggest box wouldn’t hurt.
