 Press <kbd>R</kbd> to run the script in the current directory.
 
+It's possible to run multiple scripts with `nnn` as long as the scripts are in the same location and share the same prefix. To enable multiple scripts,
+
+    export NNN_MULTISCRIPT=1
+
+With the example of `NNN_SCRIPT` above, some more scripts could be:
+
+    /usr/local/bin/nscript1
+    /usr/local/bin/nscript2
+    /usr/local/bin/nscriptcustom1
+    /usr/local/bin/nscriptcustom2
+    and so on...

+Type the correct suffix  when prompted on pressing the keybind <kbd>R</kbd>. To use the base script (`NNN_SCRIPT`), just press <kbd>Enter</kbd>.

 #### change dir color
 
 The default color for directories is blue. Option `-c` accepts color codes from 0 to 7 to use a different color:
