CONTROLS

Change a control's name when a key is pressed

Try something like this.

LOCAL FN keyDown
  DIM KeyRecord (7)
  CALL GETKEYS(KeyRecord(0))
END FN = FN BITTST(VARPTR(KeyRecord(3)),13)

WINDOW 1, "button test", (3,41)-(509,338),1
BUTTON 1,_activeBtn,"Add Name", (10,30)-(120,50)
PRINT "Press + to end."

WHILE gProgramEnds = 0
  HANDLEEVENTS
  optKeyDown% = FN keyDown
  LONG IF optKeyDown%
    LONG IF gOptFlag% = _false
      BUTTON 1,_activeBtn,"Import Names"
      gOptFlag% = _ztrue
    END IF
  XELSE
    LONG IF gOptFlag% = _ztrue
      BUTTON 1,_activeBtn,"Add Name"
      gOptFlag% = _false
    END IF
  END IF
WEND

' this code shows how to do what you asked for --
' to change a button-label when the option-key is pressed.
' i think your code didn't work because
' the option key doesn't put a keypress event in the queue.

You need to work in an ON EVENT function and not discriminate among events, i.e., check the state of the option key whenever your ON EVENT function is entered.

LOCAL FN DoEvent

  theEvent = {EVENT}
  thePoint;4 = EVENT+_evtMouse
  modKeys;2 = EVENT+_evtMeta
  optDown = modKeys AND _optionKey%

  LONG IF optDown
    LONG IF gOptFlag% = _false
      BUTTON 1,_activeBtn,"Import Names"
      gOptFlag% = _ztrue
    END IF
  XELSE
    LONG IF gOptFlag% = _ztrue
      BUTTON 1,_activeBtn,"Add Name"
      gOptFlag% = _false
    END IF
  END IF

END FN
