Hi Jukka, Thanks for clarification, every answer makes sense
Michaël >> I try to follow interesting Jukka's input, but I don't use editing tools >> as much... >>> I list some quick notes about digitizing with OpenJUMP and some other >>> programs. >>> 1) - Before Ede implemented the new keyboard shortcuts the only way to >>> cancel digitizing was to reselect the same digitizing tool or some other >>> tool from the toolbox or Select features or Fence tool from the main menu. >>> - With the new keyboard shortcuts we have now, selecting another tool >>> does not cancel drawing but the only way to cancel digitizing is to press >>> Esc when the same tool that was used to start drawing is active. >>> - Behaviour is clearly different.
