Concepts saves every stroke, allowing for unlimited undos. You can undo or redo actions using buttons, gestures, or a stylus shortcut.
Undo/Redo Buttons
On the Tool Wheel, tap the backward-curving arrow to Undo or the forward-curving arrow to Redo. If the Tool Wheel is docked, you may need to spin it to find the buttons.
Gesture Shortcuts
By default, you can use a two-finger tap to Undo and a three-finger tap to Redo. You can customize these shortcuts in the status bar under Settings > Gestures.
Stylus Shortcut (iOS only)
If you use a non-Apple Pencil stylus with a shortcut button, you can assign it to Undo. Connect your stylus, then go to Settings > Stylus to set the shortcut.
