General Tips

  • Switch tools quickly: Use single-key shortcuts to switch between tools without reaching for the toolbar
  • Zoom in for precision: Small objects and fine boundaries benefit from zooming in before drawing
  • Use undo liberally: It is faster to undo a mistake than to manually correct it
  • Review at full zoom-out: After annotating, zoom out to verify nothing was missed
  • Keyboard over mouse: Almost every action has a keyboard shortcut; learning them significantly speeds up annotation
