Atlantis allows you to undo any operation that you perform with your documents: typing, deleting text, formatting etc.
So if you have accidentally made some undesirable changes to your document, Atlantis is able to back your document to the previous state.
Atlantis tracks all changes made to the document, and is able to undo a huge sequence of operations made to this document.
To undo the most recent operation that you made on the active document, click the button on the toolbar of Atlantis.
Also you can choose the Edit | Undo command, or press the Ctrl+Z or Alt+Backspace keys.
You can undo as many recent operations as you require. For this repeat clicking the button or pressing the above hot keys until the required state of your document achieved.
Undoing all the operations performed on the active document, is a breeze. Simply click the button on the toolbar of Atlantis, or choose the Edit | Undo All command.
Atlantis allows you not just to undo operations but to redo the undone operations too. For example, you might undo some operation accidentally or simply change your mind about the recently undone operation.
To redo the most recent undone operation, click the button on the toolbar of Atlantis.
Also you can choose the Edit | Redo command, or press the Ctrl+Y or Ctrl+Shift+Z or Shift+Alt+Backspace keys.
You can undo as many recently undone operations as you require. For this repeat clicking the button or pressing the above hot keys until the required state of your document achieved.
You can also redo all the undone operation at a single mouse click or key pressing. Simply click the button on the toolbar of Atlantis, or choose the Edit | Redo All command.
The Group Undo option (the Tools | Options... command, Edit tab) controls how the text typing is undone / redone.
When this option is on, Atlantis undoes / redoes such operations by whole words.
When this option is off, such operations are undone / redone "character by character".
Another option – Undo After Save option (the Tools | Options... command, Edit tab) – enables or disables undoing operations after a document is saved.
When this option is on, you could undo operations even after you have saved your document so that you could back your document to the state in which it was before saving (we recommend to turn this option on).
