The directory ~/.ratmenu contains the main menu file menu.sh, and the submenus it calls; all these are editable scripts. We will now edit the Network menu using GVim. GVim is in the menu, but try calling it using the colon (C-t :)

:exec gvim ~/.ratmenu/network.sh

or simply

C-t ! gvim ~/.ratmenu/network.sh .

Note that graphical applications are called directly, but command line programs need to be opened inside a terminal.

Use j and k to navigate to where you want to add the entry for Alpine, type i to insert, ESC to return to command mode, and :wq to write and save. Test the change by typing C-t r - the new item should already appear. If all is well, you may close the editor.
