I use helm-M-x and helm-descbinds to show functions and keybindings I can execute. I would like to be able to see the help for a function without having to ESC, C-h f, retype function. (Like this answer for smex).
Defining a key as part of helm-map (even after emacs has loaded) doesn't work for me:
(define-key helm-map (kbd "C-u") 'describe-function)
I get this:
helm: Error: Trying to run helm within a running helm session
(Running describe-function from M-x opens helm.)
This helm intro says:
If helm-mode is activated...
C-h f, which runs describe-function, automatically takes the symbol at point as default for searching function.
Does that mean
C-h f should work in the helm minibuffer? Or is it referring to other functionality?
How can I invoke other commands on the helm results?
(I use spacemacs on Emacs 24, but I don't think that matters?
