**UPDATE - 10/14/06** One of the commands available, not documented in the 50g material, but documented for several earlier HP calculators, is a KEYTIME command. Quite simply, replacing the default keytime with "500" eliminates missed keystrokes. This corrects the problem I described above. Where do I find this KEYTIME command that this other user stated?? I really want to fix the "missed keystrokes" problem. Thanks.
