the editor needs a read-only mode. in this mode, cursor navigation 
would work as normal, but any attempt to modify the content would 
pop up a confirmation dialog requesting to switch the mode.
the mode would be initialized from the file's access rights. a 
manual toggle (and possibly a command line switch to be able to use 
the editor as a viewer) would be provided.
