Space Bar activates Geo Location Request

Spacebar doesn't complete command and return to arrow

On Mac, when Accessibility is turned on, it’ll intercept space bar. You’ll see this by System Preferences->Keyboard and the Shortcuts tab, where tab moves keyboard focus between “All Controls”. If you change this to “Text boxes and lists only”, or type Ctrl-F7, it wont interfere. However, you miss the little blue silhouette and the ability to use space bar to click on the blue-halo selected item.
