Details
A history of the key code for the last pressed front-panel key is maintained by the instrument. When
the instrument is turned on, or when it is transitioning from local to remote operation, the key code is
set to 0 (display.KEY_NONE).
Pressing the EXIT (LOCAL) key normally aborts a script. To use this function with the EXIT (LOCAL)
key, you must set display.locallockout to display.LOCK.
The table below lists the keyCode value for each front-panel action.

numeric value of 103). This allows for better forward compatibility with firmware revisions.
