I find myself temporarily without a Wacom Tablet so I wanted to play with the software using a mouse-only setup (like I did in the early to mid 90's). In Photoshop and virtually all art programs I've ever used you can ink/draw by using this method: Draw a point, hold the SHIFT key on the keyboard and draw another point. At this time the software usually will draw a straight line between the two points, or if you prefer you can hold shift the entire time and draw a perfectly straight line. This allows you to do curves and digital inking quite well with vector lines and then you can always bend/change/edit the lines later to fit your artwork.
When I try this in OpenToonz however, I simply get two dots and no line between, so it seems that the SHIFT trick doesn't work. Does anyone know how to get this to work in OT? Please let me know, thanks!
