The Ctrl+ Arrows shortcut to switch between different workspaces in MacOSX is the perfect exemple for how annoying it could be.Being in Safari, as a windows user at work, i'm really used to do Ctrl + left arrow to go back to previous word in Firefox. If i do so under MacOS X, it changes workspace... AAAHHHH !!! For people used to work on softwares like Photoshop or Flash, i know how too much system shorcuts can be a misery in daily use. -1 for Alt + Left/Right Arrow based system shortcut
