The Select All command selects all visible objects in editable layers and classes. The active layer is always editable, but other layers can be editable if they are visible and if the Layer Options are set to Show/Snap/Modify Others. For more information about setting layer and class visibility and layer and class options, see Setting Visibilities in the Organization Dialog Box, The Visibility Tool, and Setting Visibility with Class and Design Layer Options.
To select all objects in the drawing area:
Select Edit > Select All.
Alternatively, right-click (Windows) or Ctrl-click (Mac) on the drawing area, and select Select All from the document context menu. The keyboard shortcuts for this command are Ctrl+A (Windows) or Cmd+A (Mac).
The program selects all visible objects that can be modified. Each of these selected objects is displayed with highlighting. Locked objects are also selected so they can be unlocked for modification.
