TeX-find-macro-{start,end} both return nil if point is not on a macro or
in one of its arguments. E.g., in
This is some \textbf{sample|1| text} bla|2| bla.
it'll work at position |1| but not at |2|.
So maybe you want to have your lambda cater with that situation:
--8<---------------cut here---------------start------------->8---
(lambda ()
(interactive)
(let ((pos (TeX-find-macro-start)))
(when pos
(goto-char pos)
(search-forward "{" (TeX-find-macro-end) t))))
--8<---------------cut here---------------end--------------->8---
And you don't want to bind these TeX lambdas to global keys. Use
something like:
--8<---------------cut here---------------start------------->8---
(add-hook 'TeX-mode-hook
(lambda ()
(local-set-key (kbd "C-c a")
(lambda ()
(interactive)
(let ((pos (TeX-find-macro-start)))
(when pos
(goto-char pos)
(search-forward "{"
(TeX-find-macro-end) t)))))))
--8<---------------cut here---------------end--------------->8---
Bye,
Tassilo
