keyCode
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,
display.locallockout must be used.
The table below lists the keyCode value for each front-panel action.

When using this function, use built-in constants such as display.KEY_RIGHT (rather than the
numeric value of 103). This will allow for better forward compatibility with firmware revisions.
The OUTPUT ON/OFF control cannot be tracked by this function.

key = display.getlastkey()
