How to check/peek at a function signature?

Is there any way to see the parameters for a function even if it's just in loaded files? Using list_all_functions_all_buffers seems to do it but I can't find a way to back out of the command.

You just need to close the decls buffer like a regular buffer.

That said it's not the most practical way to get functions arguments. Have a look at Ryan Fleury's custom layer, I think there is a thing were it can display function arguments of the identifier under the cursor (not sure).

Works perfectly, though the layer has way more than I want so it will take me some time to strip all of that away.
