+  * Logical buttons 4, 5, 6, 7 are usually interpreted as scroll up, down, left, right.
+  * The fourth and fifth physical buttons on a device will thus send logical buttons 8 and 9.

-Edit **~/.xbindkeysrc**.
+One approach is to create a shell script that performs the Mouse Button mapping:
-  * To create a double-click event when button 8 is released, add the following:
+<code bash>
+echo "xinput --set-button-map 21 3 2 1" > leftmouseremap.sh

-<file bash ~/.xbindkeysrc>
+Give it executable permission:
-"/usr/bin/xte 'mouseclick 1' 'mouseclick 1' &"
-b:8 + Release

-**NOTE:**  The format of this file is a series of paired lines.
+chmod +x leftmouseremap.sh

-  * The first line is a command to be executed for an event;
-  * The second line is the event description.
-Here, the **xte** component of xautomation to send events directly to the input handler.
