The D90 supports thirty user-programmable pushbuttons and ten selector switches.
Each of the selector switch instances can be assigned to one of the available HMI control
keys on the three pushbutton screens. The mapping of pushbutton instances to control
keys is fixed. Pushbuttons 1 through 10 are on the first screen, 11 through 20 on the
second screen, and 21 through 30 on the third screen. Pushbuttons are numbered starting
with the top-left control key, increasing from top-to-bottom on the left side of the display
and then from top-to-bottom on the right side of the display.
The user can specify the text for the navigation menu entry for each pushbutton page. If a
page does not contain any configured pushbutton or selector switch instances, the
navigation menu is disabled and the menu text is grayed out.
For each pushbutton and selector switch instance, the user supplies the text that is drawn
in the rectangle adjacent to the control key for each switch position. For pushbuttons, text
can be specified for both the ON and OFF states.
The pushbutton configuration is started when the user clicks the Configure setting in the
user-programmable pushbutton settings window.

The D90 must be in the programmed state and the corresponding selector switch or
pushbutton element must be enabled before the control keys will affect a change to the
element state.
