This morning, I'm watching one of the first videos on the Toon Boom Tips page, which teaches viewers about the interface of Animate Pro and Storyboard in three 10-minute long videos. I wanted to pick up some small tricks to speed up my workflow.
Tip: While using Brush tool, hold down 'O' and click and drag the cursor to set the maximum size of the brush stroke (when pressing hard with the stylus) manually. To set the minimum size (when pressing lightly with the stylus) press 'Shift' and 'O'
Tip: when using the Line Tool, hold down 'Shift' to move the line around in straight increments. If using the Brush, hold down 'Shift' to draw a straight line.
ETA: Since the videos must have been made a couple of years ago, a lot of the information they base themselves on is not relevant to the current version of Storyboard Pro, so I have used strikethrough on the above points which are no longer of use.
