'qspl' RETURN 'w'|'s'|'q'
This keyword is used to split one or more lines at a certain position (can also be done with ”qlin”). A point is created at the splitting position, the original line is deleted and two new lines will appear instead. All lines running through the selected location are splitted at once and the newly created splitting points will be merged to one if they are closer to each other than defined by ”gtol”. To split a line move the mouse pointer over the line and press the ”s” key. Press ”q” to quit the command. There is no undo but lines can be combined with the ”qseq” command.

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.
