Current Documentation

Currently says: "Press Space, Enter, or Escape to dismiss the answer and return to the prompt."

What's Wrong or Missing?

Doesn't mention the "press f" option to fork a /btw

Suggested Improvement

1. Mention the option exists
2. Explain what forking actually does
3. Add example of a forked dialogue

Impact

Low - Minor confusion or inconvenience

Additional Context

Local session shows the option. Just a documentation gap. Caused a confusion in my local session when reviewing previous planning sessions. Local session checked the docs and gave me:

"On /btw: per what I dug up, it's meant for quick asides that don't bloat the current session's context — not for forking. Your build-vs-buy pivot in Session 1 was a genuinely new direction, so /btw probably wasn't the right tool there; a fresh
session (claude / claude -c) would have been cleaner. Use /btw for "noting a thought without derailing", not for "starting a new line of inquiry". (Caveat: I'm relaying a guide lookup, not first-hand verification — worth a quick /help if it matters.)"

After pressing it with ""/btw" I'd like to push back on since it has a fork option I assumed I was using it correctly" it returned
"Conflict — my second lookup also found no fork option in the official /btw docs. The docs describe it as an ephemeral side-question overlay that doesn't enter conversation history, full stop. The guide agent suggested you might be thinking of /branch
(which actually forks a session, inheriting context up to that point), or that a plugin/skill on your machine extends /btw.

Worth a 10-second check next time you hit it: if the picker offers multiple actions, screenshot or note the option labels — that'll tell us whether it's a built-in I'm missing, a plugin extension, or /branch you'd been reaching for. Until then I
genuinely can't tell which of us is right, but if you saw a fork option in the UI then something on your install offers it."
