On second reading, the documentation ("IDL> ? abbreviating keywords") exactly
describes Craig's suggestion. The full keyword TIME cannot be abbreviated to a
shorter unique length, whereas TIMESTEP can be abbreviated to the shortest
unique lenght TIMES. Nowhere in the documentation can I find the behaviour that
the keyword TIME may not be used, simply because... because... well, for no reason
at all actually. So I would consider this to be a bug, not a policy.

I fully agree, *if* you are referring to the general (over-)use of keyword abbreviation.

Yes it does. That's what keyword abbreviation is all about.

:-) .  `Feature request' was the wrong wording. I should have said `bug report'.
Paul, would you take the honours? :-)
