How to Undo/Redo Changes on Your Page
The History feature in the Tools menu lets you undo or redo changes you've made.
Step 1: Edit your page using the Lime Editor
Step 2: On the Tools menu, click History
Step 3: Click any item in the list to return to that layout. You can keep selecting different points to undo or restore changes.
Step 4: Once you're done editing, click Done then Publish
Note: When you publish the page, the history is cleared, so you won’t be able to go back to any changes you didn’t keep. If you save the page as a draft or discard your layout, the history stays, and you can undo or redo changes the next time you edit the page.
Remember, you can use the Revisions feature to go back to a version you published earlier.
