You can reverse the previous action by using the Undo command. You can also reverse the action of the Undo command by using the Redo command.
From the Edit menu, select Undo or press Control+Z.
Each click reverses one more action. Continue clicking Undo (or pressing Control+Z) to remove as many of the previous changes as necessary.
Tips:
When the Undo command
is unavailable (dimmed), you cannot undo the previous action.
Captivate tracks actions from the time you open a project
until the time you close the project. Therefore, you can undo as many
times as you need to, as long as the project remains open.
After you have used the Undo command, from the Edit menu, select Redo or press Control+Y.
