MF + ATS 3/9/09: As with predictive text, is there a standard for the number of letters typed in before suggestions appear?
PLS: (3/10/09): Not a "standard" per se, but many systems wait until you have three or more. This is more a function of performance, since with a single letter, you may be selecting 1000's of possibilities. Hybrid models are possible - we should talk.
