       'qdiv' RETURN 'w'|'a'|'i'|'1'-'9'|' 10'-' 99'|'q'

This keyword is used to change the division of a line by pressing a number between 1 and 9 when the mouse pointer is at the position of a line (see also div). To define numbers between 10 and 99 press the space bar when the mouse pointer is at the position of a line and then the number. To select more than one line with one stroke, type ``a'' before and create a rectangular picking area by pressing two times the ``r'' key. Both strokes define opposite corners of the rectangle. To select only one line type ``i'' before. Press ``q'' to quit the command. General rules are described in ``div''.

It is also possible to measure distances between two pixels on the screen. Just press the key ``w'' on the positions of the two pixels. The distance is calculated in the scale of the displayed geometry.
