Set up and Undo

1

Let’s start with finding Undo. This threw me at first because I assumed it was a two-finger tap gesture. It can be found in the bottom right, along with Redo and the Tooltip Assistant. Using the Rectangle tool I draw one square and then duplicate it to make a row of three. To duplicate something tap Commands>Duplicate. Then I duplicate that row vertically to create a 10-panel layout. To change the stroke width, tap Pen and change Width. You can drag the values up and down by pressing Width or tapping it and typing values numerically.

Then I tap Use Fill to remove the colour inside the rectangles. I group all panels and lock them by tapping Layer the More (the circle with three dots) and hitting Lock. You’ll find Layer Opacity and Layer Blend Modes here, too. Ideally, these would be in the main Layers panel and not an additional tap away because we’re going to be changing and locking layers a lot in this workshop.
