Within the Sequence Wizard, the Move Item Up in Sequence button, or its shortcut (CTRL + UP ARROW) causes the selected step to be moved up, within its same nest level. If an item is already at the top of its nest level, it does not move.
For example, if a sequence looks like:
Pressing the Move Item Up button causes the selected item, Potentiostatic EIS, to be moved up, yielding the result pictured below:
The Potentiostatic EIS step now runs BEFORE the Potentiostatic step, rather than after.
Pressing the button again causes no change to the sequence, because the Potentiostatic EIS is now at the top of the sequence.
