Inside the birds group after a double click: one bird selected, and the Document tree expanded on the group

Double-clicking an object

A double-click asks the tools whether they can open the object:

Lines, dimensions and arcs do not need a double-click: their handles — the endpoints, the arc grips — are there as soon as you select them. The same goes for the anchor points of the guide of a spine, of a brush stroke, of an array on a path and of area type or type on a path: you see them by selecting the modifier, and the double-click is for entering it.

Inside a container

  • The children stay where they were and the view does not move.
  • The rest of the document is dimmed, under a veil the color of the canvas: it cannot be picked or selected.
  • What you draw is created inside the container, and what you paste goes there.
  • Inside a clip or a mask, the clipping and mask shapes show as a dashed blue outline.
  • Inside a symbol, a pattern or a marker, you see the cross of the resource's origin.

At the bottom of the toolbar the Exit button appears, with the container's name in its tooltip.

When you exit, the container is selected. From a symbol you return to the use you entered from; from a resource opened from its panel you return to the previous view, with nothing selected.
