Autocompletion for most free Text fields

As a SMS user, I would like help to fill in text fields, so suggest selecting entries (from non-CV entries) in Short Name, Long Name, Keys, Values... from already entered values. This way I can be sure not to enter similar things like supplier in different ways. It shouldn't just be based on my own entered values ​​- all entered values ​​should be based on this field instance. When I start typing (maybe 3 letters that aren't type sensitive), autocomplete should be used - either like the CV dropdown, or better just autocomplete, so that the difference between autocomplete and the CV is clear to users it's clear.
