There is no existing way to map a MMENU symbol to a menu name -- it would have to be made.  It would take a double array: one of MMENU symbols and a corresponding one of menu names.

But... maybe this double array can also be used to make the reverse mapping?  To simplify the long if-then-else ladder in strtomenu()?  Hmmm...  Sounds like a plan.  :)

To reproduce, put "unbind ^C search" in your nanorc, and run nano.  It will fail to start and prints these two lines:

Fatal error: no keys mapped for function "Cancel".  Exiting.
If needed, use nano with the -I option to adjust your nanorc settings.

It says «no keys mapped for function "Cancel"».  Right.  But where?  In which menu?  If I've just changed one line in my nanorc, I will know.  But if I pasted a block of settings from another machine...

Expected behavior: it should mention in which menu the vital binding is missing.

(Aside: I don't think Cancel is an essential function in the Search menu: the user can just type some junk that does not exist in the file and press <Enter>, it will have the same effect.  Only when the file is huge and searching takes a significant amount of time, would having a Cancel button be useful, but still not essential -- it will just waste some time, it will not make leaving the Search menu without moving the cursor impossible.)
