Keyboard Shortcuts

• • or Numpad + — Converts the selected segment into a curved arc (or increases arc intensity).
• • or Numpad – — Decreases arc curvature or switches arc back to straight line.
• Shift (hold) — Activates zoom mode. While holding Shift, a magnifier lens appears under the cursor to help you place points more precisely.
