display.locallockout = lockout -- Writes state of lockout.
Set lockout to one of the following values:
0 or display.UNLOCK Unlocks LOCAL key.
1 or display.LOCK Locks out LOCAL key.
Remarks Setting display.locallockout to display.LOCK prevents the user from interrupting
remote operation by pressing the LOCAL key. Set this attribute to display.UNLOCK to
allow the LOCAL key to abort script/remote operation.

Function Presents a menu on the front panel display.

items Menu items to display on the bottom line.
Remarks • The menu consists of the menu name string on the top line, and a selectable list of items
on the bottom line. The menu items must be a single string with each item separated by
white space. The name for the top line is limited to 20 characters.
• After sending this command, script execution waits for the operator to select a menu
item. An item is selected by rotating the wheel (or using the cursor keys) to place the
blinking cursor on the item, and then pressing the wheel (or ENTER key). When an item
is selected, the text of that selection is returned.
• Pressing the EXIT key will not abort the script while the menu is displayed, but it will
return nil. The script can be aborted by calling the exit function when nil is returned.
Details See “Menu” in Section 14.

will be given the value Test2:
selection = display.menu("Sample Menu", "Test1 Test2 Test3")
print(selection)
Output: Test2
