* These buttons will modify only one display or signal at a time.
* To select an individual display from a multi-display screen, click on the display. The display will become highlighted with light blue to indicate it has been selected and that the Signal Control buttons have been assigned to it.  Modify the signal using the icons to the left.
* If more than one signal appears in the same display and the signal names are clickable, it means that separate scales are available for each signal and that signals can be manipulated separately. Select the signal you wish to modify by clicking on the tiny colored square next to the name of the signal within the top of the display.

A white dot in the center of a signal's square indicates that particular signal is selected. Use the Signal Control Toolbar to modify the selected signal. If the signal names are not clickable, it means that the signals have the same scale and are locked together so that the signal controls modify all signals together.
