Drawing tools
Shapes, lines, freehand, type and images

The tools are in the toolbar at the top; the letter in parentheses in each button's tooltip selects the tool from the keyboard. Almost all of them place points — by dragging, or with click and click — and ⇧ constrains them; the Pencil and the Brush record a single gesture: press, drag, release. See The two ways of every gesture.
