Causes nearly all keystrokes to be returned "raw" by setting the ctlid to the ASCII value of the keystroke and exitcode to 0. The only exceptions are the TAB, Shift+Tab, and Arrow keys, which retain their navigation function. This is similar to EVW_NUMERIC, in that the ctlid parameter is used to return a user-input code which has nothing to do with an actual control ID.
Since the returned ctlid may not have anything to do with a valid control ID, take care not to pass the value back as input to a subsequent EVENTWAIT operation (or else it will probably abort with exitcode 99, meaning invalid control ID.)
