Details
After you send this function, script execution pauses until a front-panel action (for example, pressing a key or the
navigation wheel , or turning the navigation wheel ). After the action, the value of the key (or action) is
returned.
If the EXIT (LOCAL) key is pressed while this function is waiting for a front-panel action, the script is not aborted.
A typical use for this function is to prompt the user to press the EXIT (LOCAL) key to abort the script or press any
other key to continue. For example, if the keyCode value 75 is returned (the EXIT (LOCAL) key was pressed),
the exit() function can be called to abort the script.
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, such as 103. This allows for better forward compatibility with firmware revisions.
Example
key = display.waitkey()
print(key)
Pause script execution until the operator presses
a key or the navigation wheel, or rotates the
navigation wheel.
If the output is:
8.60000e+01
It indicates that the MEAS(A) key was pressed.
