bug#44135: 27.1; Info about key used to invoke a command

[dalanicolai]

Well as someone new to Emacs, who did not read the full elisp manual yet, I thought it was somewhat logical because, as far as I am aware, the interactive spec is the place to look for how to handle mouse (click) events. I thought it might be non-expert friendly to just guide newcomers to the right place for the case of keyboard event (as it really is not very straightforward to find if you do not know what you are looking for). I am certainly no expert, but I have published a toc-mode package on Melpa, and hacked a pdf-continuous-scroll package, but I still had never heard of the command loop. Anyway, I trust you made the right judgement. Thanks of course for your reply.
