Variable references and page-awareness #826

There are some commands (like the summary) that are based on the page content. When I create a new command, for example, {{selection}} appears as placeholder. What other variables can be used? Which variable is based on the page content? {{page}} doesn't work for me.

So my main question, is it possible to chat with current page content? If so, how?

An edit button would be nice for the predefined commands to see what prompts are those based on.

Another thing here that it says for me that GPT does not have web access. Is this normal?

Thanks :)
