# History
Karedi lets you undo & redo practically any change that you have made (up to 1000 actions back). The list of the last actions that were taken is visible in *History* tab which is located above the [*main editor*](/karedi/user-interface/middle-components/main-editor.md) and between the [*tracks manager*](/karedi/user-interface/upper-components/tracks-manager.md) and [*lyrics editor*](/karedi/user-interface/upper-components/lyrics-editor.md).
The newest actions are displayed at the bottom and the last applied action is selected:
## Undoing changes
To undo your changes you can either:
1. Press `ctrl + z` shortcut
2. Click *Undo* icon in the [toolbar](/karedi/user-interface/toolbar.md)\
3. Go to menu Edit -> Undo
3. Click on the action that you want to go back to in History tab:
As you can see undoing operation changes which action is selected. The selected action always points to the last applied action.
