how to use keyboard for mouse functions in linux X window system.

You enable and disable it by hitting control-shift-numberlock.
Apparently the speaker should beep but mine never does.

Then you use the number pad to move around:

/ * -   select mouse buttons: first, second, third in that order
. 8 .   becomes         .       up      .
4 . 6   becomes         left    .       right
. 2 .   becomes         .       down    .

Holding one of 2,4,6,8 down and pressing number 5 down speeds the mouse
up.
Pressing 5 down on its own does a mouse click with the current button.
Pressing + down on its own does a double-click with the current button.
0 clicks and holds down the current button.
. releases the button that 0 held down.
