Re: shortcut for tables..

The theme of discoverability is very important for an editor that can be
fully keyboard-driven. A helpful discoverability feature would be
autocompletion of \commands. One (at first unintuitive) way to do it is
like the helm emacs package <https://github.com/emacs-helm/helm> to narrow
down options (there are many others, e.g. ivy <https://oremacs.com/swiper/>,
with different philosophies, I am not an expert).

Álvaro.

PS. apologies if it seems like a thread hijack.
