How-to: Enable Expose and Spaces for the Magic Mouse

magicmouse

So you’re loving your brand new Magic Mouse but are missing the ability to activate Expose and Spaces right from the mouse? Not to worry, we’ve got you covered. Using SIMBL and a neat little preference pane called MultiClutch, we can map our own custom shortcuts to the left and right swipes coming from the Magic Mouse and have them activate Spaces and Expose instead of navigating forward and back.

Getting Setup

The first thing we need to do is to get MultiClutch up and working in a 64-bit Snow Leopard world. MultiClutch, like a lot of apps relying on InputManagers, kind of got gimped when the new big cat showed up. Luckily though, a recent fork in the project now allows for its plugin to be loaded through the latest SIMBL release.

You can find some detailed instructions on how to get MultiClutch up and running from the source of the new plugin, but essentially what you need to do is:

  • Install the original MultiClutch application.
  • Install the latest version of SIMBL.
  • Download the forked version of the MultiClutch plugin and load it into the SIMBL plugin directory at /Library/Application Support/SIMBL/Plugins.
  • Go in and remove the old version of the MultiClutch plugin from /Library/InputManagers.

Adding Shortcuts

Once you have MultiClutch up and running, open its preference pane and add new gestures for Swipe Left and Swipe Right and then assign them each key commands. If you’re configuring for use with Spaces and Expose you’ll have to use one of the function keys. You may have to do some shuffling around depending on what function keys you already have mapped. I used F1 and F2 as they weren’t already mapped to anything.

MultiClutch

Then just go into your preferences for Expose and Spaces and set Activate Spaces and All Windows to the corresponding key command you used in MultiClutch. Since we’re using SIMBL you’ll have to quit and relaunch any applications that were already active when we started in order for the system to pick up our new shortcuts when that application is active.

Caveat Emptor

Obviously this is not an ideal solution, and ultimately it would be best for Apple to build in some customization options for Magic Mouse gestures right into the Mouse preference pane. As with anything that is this hacked together, your milage may vary, but I’ve been using it for a couple days now and it’s working great. On the whole I really love the new Magic Mouse but not having my Expose and Spaces was a bit of a deal breaker for me. Hopefully this will at least be able to tide us over until a more solid solution comes along.
