Quicksilver , the app launcher and all-round productivity-enhancing wonder app, is full of surprises.

Just when you think you are getting on top of it, some little thing comes along to remind you how little you know of its mysterious wonderfulness.

A few days ago I read something on the Quicksilver forum that was completely new to me. Simple. Smart. But utterly unknown to me.

If you hold a keystroke down for a few seconds it actually launches the selected app without the need to hit the Enter key. How about that?

Just hold down the “m” key and Mail launches:

Wonderful. Quicksilver is a like a box of chocolates. You never know what you’re gonna get.
