Change Mission Control Animation Speed (Mountain Lion)

It's possible to change the time it takes for Mission Control to complete its animation. I'm all for decreasing animation times in Mountain Lion, so this is a handy tweak if you're interested in a similar thing.

In Terminal, type the following:

defaults write com.apple.dock expose-animation-duration -float 0.1  ; killall Dock 
where 0.1 is the time; you can set it to any number you want; try several different numbers to see how this changes the animation. Press Return, and Mission Control's animation time is changed.

To revert it back to the default, enter the following in Terminal, then press Return:
defaults delete com.apple.dock expose-animation-duration ; killall Dock 
[kirkmc adds: This is one of those hints that is, in part, "because we can," but I do understand the desire to make certain animations a bit snappier.]
