Subtools and modifiers
Some tools come in a few variations. Their subtools open in a strip beside the rail, and you pick one: Shape's rectangle, circle, triangle, line and arc, or Fill's three smoothing levels.
A modifier is different. It's a round button on its own under the subtools, and it switches a behaviour on or off for whichever subtool you've picked.
The Pen Tool's Close Path is an example, toggling it on/off will enabled/disable automatically drawing a line from the start of your stroke to the end.
A lit modifier stays on until you tap it again.
