I have another app running that has a window up whose title is 'Password' so I can find it. However, how can I send a keystroke to it programmatically once I locate the window?

Look at the below code in the larger code section:

   DO WHILE CheckWin('Password')
      *--THIS WORKS BUT I NEED TO SEND KEYSTROKES TO IT SOMEHOW
      WAIT WINDOW "Found the password window" NOWAIT
   ENDDO

I can locate the window but I cannot send keystrokes to it. Is it possible?

TIA!
