Move the mouse cursor with keyboard
You can use your keyboard for moving the mouse cursor in the X Window System. This means you can use the mouse without touching it at all.
< Moving the cursor >
Of course you must have the X Window System running first… Then press Shift + NumLock to turn the feature on.
Move the mouse using the 1, 2, 3, 4, 6, 7, 8, and 9 keys in your number pad. Take a look at your number pad, and you’ll quite quickly figure out which key moves the mouse in which direction.
< Clicking >
Click by hitting the 5 key on your number pad. Double click by hitting it twice.
