In a C# lsp-mode buffer, when something is highlighted, is there a "jump to next warning or error" function?

I don't see anything like lsp-next* or lsp-jump*.

Any pointers?

lsp-mode integrates with flycheck or flymake. Please check the variable lsp-diagnostics-provider.

For example, flycheck provides flycheck-next-error and flycheck-previous-error to help navigate across errors/warnings. You can also use flycheck-list-errors to see the errors list. Similarly, flymake provides flymake-goto-next-error and flymake-goto-prev-error.


For real-time diagnostics, lsp-mode utilizes either flycheck or a built-in package flymake (in Emacs open manual with C-h R flymake RET).

flycheck documentation on interaction with errors states:

By default Flycheck hooks into Emacs’ standard error navigation on M-g n (next-error) and M-g p (previous-error).

This is what, supposedly, you're looking for, since flycheck is a recommended package for use by lsp-mode and is configured by default.

flymake documentation in its turn also describes how to navigate between errors. To reach this section in Emacs use M-: (info "(flymake) Finding diagnostics") RET. Now the section states the following:

‘flymake-goto-next-error’ and ‘flymake-goto-prev-error’ are let you navigate to the next/previous erroneous regions, respectively. It might be a good idea to map them to ‘M-n’ and ‘M-p’ in ‘flymake-mode’, by adding to your init file:

 (define-key flymake-mode-map (kbd "M-n") 'flymake-goto-next-error)
 (define-key flymake-mode-map (kbd "M-p") 'flymake-goto-prev-error)

And, since we've touched the subject of diagnostics, you may find a list of related lsp-mode custom options useful. Especially note lsp-diagnostics-provider custom option on that list, which can be used for selecting -- as its name broadly hints -- one of the mentioned providers of the diagnostics.
