Have you ever noticed that when you press an arrow key to move your cursor in one direction or another, the cursor thinks about it for a second and then goes? Hel-LO! Can we shake a leg here?
Light a fire under that cursor by adjusting your keyboard delay. Open the Control Panel (Start, Settings, Control Panel), double-click Keyboard, and on the Speed tab, move the Repeat Delay all the way right, to Short. While you’re at it, adjust that Repeat Rate to Fast, if it isn’t already. Now take your cursor for a test spin in the white text box.
That’s more like it. Click OK to keep the change.
