The options bars
What appears below the toolbar

The regular polygon tool in hand: its options bar, Sides and Frame, below the toolbar, and a pentagon just drawn

Two ways to open

  • With the tool selected: the bar opens when you pick up the tool and stays open as long as you hold it — Pen, Pencil, regular polygon.
  • On hover: it opens when you move the mouse over the button and closes when you move away, even with the tool selected — the arc modes, the list of brushes, alignment, snapping.

A tool's settings (the arc mode, the sides of the polygon, the Pencil tolerance) are kept from one drawing to the next.
