Autocompletion Event-Text

Is it possible to register somehow an input listener when the user tries to enter the event text?
I would like to implement a kind of “auto-completion” based on a set of strings stored in the database. If the user e.g. enters “Hom” he should be able to select e.g. Home. Or “Off” = Office and so on.
What is necessary to realize this functionality?
Thanks!

a) you can create your own form section - in such case you will be able to control any aspect of edit activity.
