Guides, grid, target paths, selection edges, slices, image maps, text bounds, text baselines, text selections, and annotations are nonprinting Extras that help you select, move, or edit images and objects. You can turn on or off an Extra or any combination of Extras without affecting the image. You can also show or hide Extras by choosing the Extras command in the View menu.
Hiding Extras only suppresses the display of Extras. It does not turn off these options.
To show or hide Extras, choose View > Extras. A check mark appears next to all shown Extras in the Show submenu.
To turn on and show an Extra from a group of hidden Extras, choose View > Show and choose an Extra from the submenu.
To turn on and show all available Extras, choose View > Show > All.
To turn off and hide all Extras, choose View > Show > None.
