+## Mouse Binds
+Mouse binds are binds that heavily rely on a mouse, usually its movement.
+They will have one less arg, and look for example like this:
+
+```
+bindm=ALT,mouse:272,movewindow
+```
+
+this will create a bind with <key>ALT</key> + <key>LMB</key> to move the window
+with your mouse.
+
+*Available mouse binds*:
+| name | description |
+| movewindow | moves the active window |
+| resizewindow | resizes the active window |
+
+*Common mouse buttons' codes:*
+```
+LMB -> 272
+RMB -> 273
+```
+
+*for more, you can of course use `wev` to check.*
