Xenakios,

Thank you - I really appreciate the generosity of your input and assistance.

I'd come back online to ask about the key-commands file (like "where is it?") as I'd had little luck looking at the key-commands file that opens in REAPER's Preferences (apart from seeing what could be possible).

Anyway... Then I saw your lates post - so now I have a different question!

I've looked at the .h and found, for example, this:

extern void (*CSurf_SetTrackTitle)(MediaTrack *trackid, const char *title);

Is this what I need? If so what do I need to do with it? If not, could you please give me some more pointers on what I need to be looking for?

Again, with your and SWS' help I've been able to get this far - I've no idea if how long it would've taken without your assistance!

Thanks again!

Edit: Sorry - I have pasted an example that is app.->surface... sorry! I'll repost another command that is surface->app.

Edit 2: What is this telling me? #define ID_MARKER_NEXT 40173
