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.
