Fig. 4 Setup of the softkey area
A softkey in its normal state, where its function is available, is coloured grey with a 3D
border.
A softkey that is disabled, because its function is not
available, is coloured grey without
a 3D border. Softkeys may become disabled because of the state of the instrument or
because other settings disable the function associated with the softkey.
A
n active softkey (highlighted in green) is used when the softkey selects an item or
view. For example, the GENERAL SETTINGS softkey will be highlighted green when
the General Settings view is displayed.
A toggle softkey is used to change the value of a parameter that has only two states.
Each press of the softkey toggles the value of the parameter. The current parameter
value is highlighted in green in the lower half of the softkey label. For example, in the
marker menu, the MARKER softkey will have either NORM or DELTA highlighted in
green depending on whether the marker is a normal or delta marker.
When no function is assigned to a softkey then no softkey label will be shown.
