Keysight x-series Instruction Manual

2 User Interface
2.12 Undo/Redo
When you press the Redo icon or Ctl and the Undo hardkey, you are notified with an
advisory popup message; for example, if the Center Frequency had been 300 MHz,
and you changed it to 1 GHz and then pressed Undo, the message would say:
UNDO: Center Freq 1 GHz -> 300 MHz
If you then press Redo, the message will say:
REDO: Center Freq 300 MHz -> 1 GHz
Neither Undo nor Redo perform any navigation, and have no effect on which menu
panel is displayed nor which function is active.
