Exactly. Fields or methods and helpers even if possible. I assume that exists.
Btw, the names you're giving like "FindDeclaration" where can I find these?
Maybe there's a wiki or unit header I can look at.
https://wiki.freepascal.org/Codetools
And then look at the examples in lazarus/components/codetools/examples.

For example VScode lets you hover over a symbol name like TObject and a window
will popup that shows the declaration in code, like a mini-editor that goes to
the line where the declaration starts in that file. It's basically the same as
opening a new tab/window but it's more for really quick references. I'm not
sure how it's implemented in LSP but maybe you could return the line number and
file name and the client does the rest.
FindDeclaration gives you the line and column. You can also get the source span
of the declaration.
And there is FindSmartHint, which returns a brief text for a declaration
including some context like type/var/const, private/public, parent class, etc.
Seems like exactly the code lens functionality :-)
Michael.
