How to write tooltips

In review58351002 Pokoli raised questions about the using of different terms in X2Many fields.

For the general use of “Add…” for the description of relational list fields Many2Many and One2Many I need some help:

  1. Initially in an empty list field the usage is adding lines from already existing records.
    So the “Add…” seems an adequate term for the list tool tip.

  2. In an already filled list field (filled already by a user or internal by XML), “Add or remove…” (or “Add or delete” in a One2Many) seems a better term for the list tool tips.

  3. Open a form view from an entry in the list view and creating or editing its content is a common shortcut for power users.

  4. The specific functionalities in a list can be different (read only, access, …)

I am looking for a general term for adding/removing/deleting
lines to the list and creating/editing a single line, regardless the specific implementation of the field and if it is already filled or not.

For me “Manage…” is a adequate term for the list tool tip.

And as thinking about, I find “Manage” term would fit better for all relational fields, as they all provide adding/creating and removing new entries and changing filled entries.
