F3 causes the insertion of two objects in your document: a table and a formula.
These object are visible in the Navigator (
F5) under categories Tables and OLE Objects. But even renaming them with right-click and
Rename will not change the way they are displayed in the cross-reference insertion dialog.
The only way I can see to have a user-friendly name which is not part of the insertion is to use bookmarks. Any other trick, such as AutoCaption or adding hidden text will be kept through the insertion.
Consequently, after having created your formula and numbered it, select what you want to retain in the reference and
Bookmark. Give a name of your choice.
Referencing the formula is done with
Cross-references, Bookmarks Type, Reference.
Note: I think there is a design flaw in
F3 because the formula counter is Text which could conflict with other usages. Authors should have defined a new counter like Formula.
