 POCSAG uses FSK with 4.5kHz frequency shift, at 512, 1200 or 2400 baud.
 High frequency is typically 0, with low 1, but occasionally this appears to be reversed, so the demodulator supports either.

+- Match message only: When unchecked, compare address and message. When checked, compare only message, ignoring the address.
+- Match last message only: When unchecked the message is compared against all messages in the table. When checked, the message is compared against the last received message only.
+
+<h3>16: Open Notifications Dialog</h3>
+
+When clicked, opens the Notifications Dialog, which allows speech notifications or programs/scripts to be run when messages matching user-defined rules are received.
+
+By running a program such as [cmail](https://www.inveigle.net/cmail/download) on Windows or sendmail on Linux, e-mail notifications can be sent containing the received message.
+
+Messages can be highlighted in a user-defined colour, selected in the Highlight column.
+
+By checking Plot on Map, if a message contains a position specified as latitude and longitude, the message can be displayed on the [Map](../../feature/map/readme.md) feature.
+The format of the coordinates should follow [ISO 6709](https://en.wikipedia.org/wiki/ISO_6709), E.g: 50°40′46″N 95°48′26″W or -23.342,5.234
+
+Here are a few examples:

+
+In the Speech and Command strings, variables can be used to substitute data from the received message:
+
+* ${address},
+* ${message},
+* ${1}, ${2}... are replaced with the string from the corresponding capture group in the regular expression.
+
+To experiment with regular expressions, try [https://regexr.com/](https://regexr.com/).
