Wow. Quicksilver never ceases to amaze! You can now create mouse gestures to do anything Quicksilver can do using a plugin called Abracadabra.
It’s a basic plugin, but it’s incredibly helpful. You needn’t be working for Coca Cola, o2, Citibank or any other big corporation to benefit from this extension, it works perfectly well on a home Mac that’s just carrying out small jobs.
To use it, first, go to your Quicksilver preferences, in plugins, choose “other plugins” to find plugins that aren’t installed and check the box next to Abracadabra.
Click the plus sign by Abracadabra (you probably have to have “Enable advanced features” set to Beta in the Application settings.
You’ll now have a new menu item called Abracadabra. Select it and add the sounds you want to hear when you do a gesture that is recognized or when you make a mistake and do an unknown gesture. You’ll also want to pick a key to use with Abracadabra.
Now click the “Triggers” category in preferences and create a new trigger by choosing the plus sign at the bottom then doing something you might normally do in Quicksilver such as committing something to SVN (or opening a folder or whatever you do with your Mac).
Now change the Trigger type to Gesture, and in the drawer that slides out, draw the gesture you’d like to make in order to perform the action.
You’re done! Try it out by holding down option (or whatever key you chose) and performing the gesture. If you did it right, you’ll get cool green stars, otherwise they’ll turn red.
