Keyboard as mouse

Interesting little tidbit: You can use the keypad on your keyboard as a mouse-substitute on Linux by hitting Ctrl+Shift+NumLock. Then movement corresponds with the position of the keys: 1 moves the cursor down and left, 2 moves the cursor down, 3 moves the cursor down and to the right, etc. The 5 key equals a button press, mouse button 1 by default, but it can be toggled using the /, *, and – keys. The / key sets the 5 key to button 1, * sets the 5 key to mouse button 2 and the – key on the numeric keypad sets the 5 key to mouse button 3. Pretty useful stuff for folks who don’t like to use the mouse…
