Lock Selection parameter is turned ‘On, then:
- If you click on a grouped layer in the WorkArea
window, the Group Layer will be selected, rather
than the layer you clicked on. For example, you draw an
outline, and then group it. By default the
Lock Selectionis Off, and clicking on your outline in the WorkArea will select the outline layer. With
Lock SelectionOn, the group layer will be selected instead.
- Right-clicking on a group layer offers a context menu entry to
Select All Child Layers, which recursively selects all the layers under the current layer. If the
Lock Selectionis engaged for any group layer in the hierarchy, it stops the layers inside that group layer from being selected by this operation.
CTRL|Ato select all the Handles in the currently selected layers will select the Group_Transformation_Widget’s handles of selection-locked group layers, whereas it won’t when their
Lock Selectionare Off.
The effect of these three behaviors is for a group layer to act as if it was a primitive layer, hiding the details of its contents from selection or manipulation.
