Your specification is not crystal-clear. So I give a solution for what I understand. If this is not what you expect, edit your question to modify it (don’t use a comment, change your question which is editable, contrary to forum sites). And if you modify it, mention OS name, LO version and save format. Be aware that my solution is valid only when document is saved .odt.
User selects from some list a “word” to be used automatically throughout the document. If this “word” is changed, the document is updated accordingly.
You have to offer the choice at some convenient location, likely near the beginning of the document. It is up to you to decide if you do it at the first occurrence or in a “preamble part” of the document, taking care not to print this ancillary part which will show directives about how to user-configure the document.
You need to define an input list field:
-
Insert
>Field
>More Fields
, Functions
tab
- select Type Input list
- for each list item, enter it in Item and press Add
- press Insert when done
To capture the selected item, create a cross-reference:
- select the previously create input list field
-
Insert
>Cross-reference
, Cross-references
tab
-
Type Set Reference
- give it a Name like “category”
- Insert
Whenever you need the selected item from the input list, insert a cross-reference:
-
Insert
>Cross-reference
, Cross-references
tab
-
Type Insert Reference
-
Refer Using Referenced text
-
Selection: click on the name you’ve assigned (“category” above)
- Insert
