“Keep your mouse cursor from obscuring your text as you type with lightweight, freeware application MouseAway. MouseAway does just one thing: monitors the proximity of your mouse pointer to your keyboard cursor and, if they’re too close together, moves the mouse pointer out of the way. It doesn’t work everywhere (like Firefox, for example), but this freeware, Windows only utility cuts down on unnecessary keyboard-to-mouse movement.”
I don’t know about you, but I’ve always gotten annoyed by the fact that the mouse cursor gets in the way of my typing, all the time. This simple tool resolves this aching in a jiffy.
