If you want to control your mouse pointer with the keyboard, Windows XP provides a way:

Press Alt+Left Shift+Num Lock all at once and a prompt will appear telling you that you have activated mousekeys, select ok then you can control the mouse with the numpad.

The controls are:
1,2,3,4,6,7,8,9 = move the mouse
5 = mouse button click
+ = double click
insert = hold down mouse button
delete = release mouse button (after holding it down with insert)
/, * or – = select which mouse button the above controls will click (left, both or right respectively)
numlock = disable mousekeys
