Name
bck — Backward action of the last position in digitizing
Syntax
bck ; # back up the digitizing one position
Description
Undo the last entered position in digitizing. This command is only valid in rcd - Read from cursor-mode, i.e. while digitizing with the cursor.
An alternative way to obtain the same result is to press a d on the keyboard when digitizing is active. Use several d's to undo more points. bck is the command version, and is used in menus under a button like Erase last digitized point.
