Thanks for the reply :

1)I'm a bit "mouse averse" - I.E. I prefer tmm-prompt for
numerous reasons.
2)The Elisp manual (as far as I have found it) does not give any
working examples which have edified me.
What has eluded me so far is how to use commands as values in the
alist - this is why I introduced the topic of evaluating a string
as a command.

The formatting of this structure above makes total sense, but can
it be used for tmm-prompt.
