+
+    You can configure this by specifying the button to move to next/previous.
+    Usually these are configured as follows. If you want to use other mouse buttons, you can find their number using `xev`.
+
+    | number | button |
+    |--------|--------|
+    | 4      | scroll up |
+    | 5      | scroll down |
+    | 1      | left click |
+    | 2 | right click |
+    | 3 | middles click |
+
+    By default `previous_month_button` is 5, `next_month_button` is 4.
