      Crossing: You may select objects using a crossing window.

      eRase: You may erase an object instead of trimming while in the Trim command.

      Undo You may “undo” the last trimmed object while in the Trim command.

      The Undo and Redo tools allow you to undo or redo previous commands. For example, if you erase an object by mistake, you can undo the previous “erase” command and the object will reappear. So don’t panic if you do something wrong. Just use the Undo command to remove the previous commands.

      The Undo and Redo tools are located in the Quick Access Toolbar.

      How to use the Undo tool.

      1. Draw a line, circle and a rectangle.

      You have now deleted the Erase command operation. As a result the erased objects reappear.

       How to use the Redo command:

       Ribbon = Annotate Tab / Markup Panel / or Keyboard = wipeout <Enter>

      The Zoom command is used to move closer to or farther away from an object. This is called Zooming In and Out.

      Note: The Zoom commands are located on the Navigate Panel of the View Tab and are off by default. Select the View Tab then right click on any panel and select Show Panels, activate the Navigate Panel.

      1. Select the Zoom command by using the following:

       Ribbon = View Tab / Navigate Panel

      2. Select the img down arrow to display all of the selections.
