Some mouse movements, such as selecting something in the Document window by clicking 
or dragging, can’t be played back or saved as part of saved commands. When you make such a 
movement, a black line appears in the History panel (although the line does not become 
obvious until you perform another action). To avoid movements that can’t be played back, use 
the arrow keys instead of the mouse to move the insertion point within the Document 
window. To make or extend a selection, hold down the Shift key while pressing an arrow key.
Certain other steps also aren’t repeatable, such as dragging a page element to somewhere else 
on the page. When you perform such a step, a menu-command icon with a small red X 
appears in the History panel.

Repeating steps
You can use the History panel to repeat the last step you performed, repeat a series of adjacent 
steps, or repeat a series of nonadjacent steps. (For basic information about the History panel, 
see 
.)
To repeat one step, do one of the following:
Select Edit > Redo.
The name of this command changes in the Edit menu to reflect the last step you 
performed; for example, if you’ve just typed some text, the command name is Redo 
Typing. 
In the History panel, select a step and click the Replay button. 
The step is replayed and a copy of it appears in the History panel.

If a black mouse-movement indicator line appears while you’re performing a task you 
want to repeat later, you can undo back past that step and try another approach, perhaps 
using the arrow keys.
