HOWTO use the numeric keyboard keys as mouse in XOrg
XOrg comes with built-in mouse emulation using the keyboards numeric keypad.
 Controlling the keyboard "mouse"
Hold Shift and press Num-Lock. You may hear a short beep depending on computer and GNU/Linux flavor. You may actually have to hold Shift and Ctrl and press Num-Lock on some systems.
Laptops may require you to hold the FN key to use the numeric pad, which makes this tricky.
- 7, 8 ,9 are the up directions
- 4, 6 are left and right
- 1, 2, 3 are the down directions
- / selects the left mouse key (press it twice for a doubleclick; and thrice for a tripleclick)
- * selects the middle mouse key
- - selects the right mouse key
- Press 5 or + do to the actual mouseclick
- Press 0/Ins to press and hold the selected mouse key (e.g. for dragging something)
- Press ./Del to release the currently selected mouse key.
First select the mouse key you want to (ab)use by pressing / for left mouse key, - for the right botton or * for the middle and then press 5 to do the actual click-
Example: I move the mouse where I want it and then I want to middle click, so i press the * key and 5 to click.
 Without the mouse in browsers, etc
It is easy to navigate browsers without mouse or any sort. Just use the arrow keys, enter does what leftclick does, the menu key does what the right click does and ctrl+enter acts like the middle click.
