To undo or redo any edits in your project, simply use the arrow buttons in the toolbar just above your project. The left arrow allows you to undo and revert to a previous version of your project. The right arrow allows you to redo any edits. You can click the arrows several times to go back to where you started or to where you finished.
You can also use keyboard controls ⌘ + Z (on Mac) or Ctrl + Z (on Windows) to undo.
Note: Remember that after exiting or closing the project editor, the action history will be lost.
If you have started your project by clicking on the Responsive web and mobile layouts shortcut, after you delete a chart, map, text field, or any other object from your report, a message will appear in its place allowing you to undo the last action. No other action history is available when working with Responsive web and mobile layouts!
