I started making pixel art in Photoshop and moved from using that to using Aseprite some time ago. Both Photoshop and Aseprite have a feature (I don't know what it's called) where if you're drawing a line you can hold "shift" after placing a pixel and upon the next mouse click the program will complete the path for you (due to having shift held down).

Does Grafx2 have this sort of feature available? I don't really want to use the line tool, I like being able to alternate between placing single pixels/drawing freehand shapes and drawing straight lines quickly.

(I hope the explanation of what I'm looking for isn't too confusing!)
