+#### Dual pane
+
+Any number of `nnn` instances can be opened simultaneously using the lightweight terminal multiplexter [`dvtm`](http://www.brain-dump.org/projects/dvtm/). For example, to open 2 instances or a dual pane mode, have the following alias:
+
+    alias n2="dvtm -m '^c' nnn nnn"
+
+Note that the `dvtm` MOD key is redefined to <kbd>^C</kbd> as the default one (<kbd>^G</kbd>) is also an `nnn` shortcut.
+
 #### Selection
 
 Use <kbd>^K</kbd> to select the file under the cursor.
