Mouse keys
Mouse keys are primarily intended for people who have difficulties to move a real mouse. Hence this feature is part of the Accessability set-up in the Control Panel. But to move objects precisely, pixel by pixel (especially on large screens) this is a valuable feature for all of us.
Toggle mouse keys on / off
Enable Mouse keys in the Control Panel item Accessability options, tab Mouse. Whether Num Lock is ON or OFF for active Mouse keys can also be set.
Activate Mouse keys with LEFT ALT + LEFT SHIFT + NUM LOCK. A small mouse is displayed in the system tray.
Turn Mouse keys off by pressing again this sequence. The indicator in the system tray disappears.
Only the keys on the numeric key pad can be used (not the ordinary arrow keys!).
