it would probably have been better if your friend had used iabbrev q can iabbrev gr gramma nmap q i ^[ nmap g :write^M to define the abbreviations and maps, thus restricting them to the modes where they are really needed. > I got the error message, ``No such mapping'' even though the maps command > clearly listedd q as mapped to write.

For me Vim's reply is E492: Not an editor command: can No remapping took place, but "can" is not a recognized command. > Multiple abbreviations or maps of the same letters is not a problem, within > maps or ab alone -- ordinarily last definition wins. > > What seems to be needed is a version of abbreviate that says ``only abbreviate > these letters, do not use them to map a command''.

There are also [ic]noreabbrev variants which would prevent the right-hand-side of an abbreviation to be re-used as the left-hand-side of a mapping.
