The easiest way to manage markers is to turn one on and use the mouse to drag it to the desired position. The marker tool bar is shown in Figure: Marker and Limit Tool Bar. Markers number 2 and number 8 are On in the figure. Markers can be set to an exact value by pressing the “e” button, which displays detailed marker controls, numeric value entry, peak find, and valley find.

The dark button on the right turns on the limit line. When On, it can be dragged to the desired location, or placed at an exact amplitude value by entering a number.
