Well, to cut a long story short, even the Raspberry Pi group had no answer for this as many of the proposed solutions needed menus that do not exist on the Pi. until I stumbled upon this link – solved the problem completely.
While I’m on – I’ve been reading about editors for the Pi… the one that comes with the 2 (nano) is like a step back into the last century. I downloaded something called Joe and that looks quite fine – but then when playing with a toy that someone else put me onto on my PC – that is WinSCP – which I’m now using in preference to my normal FTP client – I happened to notice an EDIT function for files on the other side of the wire – i.e. on the Pi itself. Well, it works, appears a little like Notepad, transparently downloads the file and opens for edit and when you save – sends it back. I tried some simple Python files and they worked a treat. THEN I realised I could customise the editor in winSCP – so I told it about my favourite PC editor, NotePad++ which i have heavily customised and themed. Well, it just works. So now I can editor Pi Python and other files in my normal comfortable environment.
Where there’s a will, there’s a way as loads of people probably say.
