Speed up the Mac OS X Dock Hide / Appear

This might sound silly but the 0.5 seconds required for the Mac OS X Dock to hide and appear was too long for me. I searched around a bit and found a very easy way to speed it up. In Terminal, type

defaults write com.apple.dock autohide-time-modifier -int 0;killall Dock

The dock will now fly in and out in 0 seconds. This is a very small change but it does make a difference.

If you want to reverse the change, just type in Terminal

defaults delete com.apple.dock autohide-time-modifier;killall Dock
