Undo

At the moment, Datagrok does not offer a full-fledged, bullet-proof undo functionality, however some actions could be undone by pressing Ctrl+Z:

• Changing cell value by manually editing it in a grid
• Clearing the layout (View | Layout | Clear)
• Removing selected rows or columns (Shift+Delete)
• Closing a viewer by clicking on the x icon

Maximum one operation could be undone.
