Keywords are critical to the function of the SMS Replies feature, as they are used to match a reply with the appropriate contact list or automatic appointment reminder.
EXACT can recognise multiple codes as a valid client reply. For example, you could configure EXACT to recognise all of these options as valid for a Confirmation SMS: YES, YIP, Y, YEAH, YAH, OK.
There are Guidelines for using keywords.
