+====== Run at startup ======
+One approach is to create a shell script that performs the Mouse Button mapping:
+<code bash>
+echo "xinput --set-button-map 21 3 2 1" > leftmouseremap.sh
+</code>
+Give it executable permission:
+<code bash>
+chmod +x leftmouseremap.sh

+**NOTE:**  Either run the script manually, or configure it to automatically run on system reboot.
+  * Follow any process to have this script run at boot if needed.
+  * Remember to configure 'xbindkeys' to run automatically on system startup too if needed:
+    * '/usr/bin/xbindkeys'
