On the surface this sounds like a good idea, but I think we should probe
the concept a bit deeper before we endorse it wholeheartedly. In a case
like the one described, where the step(s) the user needs to take to
activate a disabled command are few and simple, this suggestion (a
tooltip on the disabled command describing how to enable it) sounds both
useful and usable.
But what about cases where the steps needed to enable a command are
complex, lengthy, many or otherwise confusing to a novice user? Perhaps
it would be better to provide a link to the appropriate place in online
help that explains in detail why the command is disabled and under what
context(s) the command is useful and usable.
I would like to see a more complete study of this idea, with examples
from several different types of applications and of varying levels of
complexity. The concept should be fairly easy to mock up in order to
conduct some low-cost usability studies. If the author(s) of the
proposal are serious about pursuing this idea, I hope they will provide
a more complete proposed specification, with research data to back up
