Re: what is the key stroke in jaws to update a pass word in chrome?
Without knowing exactly what the dialog is saying to you it's impossible to advise.
That being said, if you are logged in to Chrome itself, all password management is done using the Google Account that you used as the Chrome login. If this is the same one you're using for Gmail, Drive, etc., then you can go directly to: https://passwords.google.com for that account, as they will be saved and managed there.

Explanations exist; they have existed for all time; there is always a well-known solution to every human problem — neat, plausible, and wrong.
