Error adding a new sequence to LaTeX-math-list

Question

Could someone help me to figure out what the template to add a new symbol to LaTeX-math-list is?

I am trying to extend the available list with two sequences, not exactly symbols; I am not sure if this is possible. So far, I ended up with the following line in .emacs

(setq LaTeX-math-list '((?\C-w (lambda () "\\Wec\{\}") "" nil)
                        (?\C-v (lambda () "\\Bec\{\}") "" nil)))

After enabling math mode, the additional keybindings are visible (with lambda at each item) but when I try to run any of them I get the following error:

Wrong type argument: commandp, (lambda nil "\\Wec{}")

I am currently learning Lisp so this is as far as I could get. Hope this is solvable. Thanks.

Answer 1

A command is a function containing an interactive form and this is, apparently, at LaTeX-math-list expects. So

(setq LaTeX-math-list '((?\C-w (lambda () (interactive) "\\Wec\{\}") "" nil)
                        (?\C-v (lambda () (interactive) "\\Bec\{\}") "" nil)))

should do the job (but I haven't tested it).
