How to get signatures for the variable at point in tuareg-mode?

Question

We can use merlin to do the auto-completion and the signature is displayed on the popup window; additionally we can use Ctrl-h or ? to get additional defined variables in the module during completion.

But for code reviewing, how can I get these signatures? I tried tuareg-list-functions and a few others, but no luck.

Answer 1

With merlin, Ctrl-c Ctrl-t. Please see the merlin emacs manual.
