Look in the documentation for the module called shortcut. This documentation mention that the last part of the line (in this case, [$Filemanager$]) is what the shortcut will execute. Now, in LS, strings between $'s are called evars (environment variables) Remember when you installed litestep, it asked you for patchs to your file manager, audio player, text editor, etc. You were deifining evars that can be found in your litestep\profiles\username\personal\evars.rc file. RC files, btw, are just plain text, and can be opened with any text editor (notepad will do fine)
