Tooltip with info that View Editor contains autocomplete

The autocomplete feature in the View Editor is a really useful feature. However, the feature is available after CTRL+SPACE (fedora). The user can miss this option. In my POV, the autocomplete dialog should appear automatically when the user is typing something (e.g. I am typing Postgres.table. and autocomplete dialog shows me the available columns). Or at least add some tooltip (as exist in the Syndesis Connections) behind ViewEditor title which will inform the user that this feature is available.
