[FEATURE]: add a command to scroll back to the user's last message

[ariane-emory]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Often I'll send a message to the model and switch windows or go AFK while the model proceeds to work and produce many pages of output. When I return, I'll want to review that output to see what it did.

Currently, I'll have to manually scroll back and forth until I find the last message I sent so that I can read on from there.

It would improve the ergonomics and UX if there were a command that would scroll the session back to the last message sent by the user. We could call it last_user_message or something like that?

I don't really care what key it's bound do, I can bind a key for it myself in my opencode.jsonc.

Have you used /timeline @ariane-emory it kinda servers teh same purpose

[ariane-emory]

@rekram1-node I have, and you are correct that it can serve a somewhat similar purpose, but it is somewhat less ergonomic:

• It requires at least two more keystrokes (<up> to wrap around from the top of the list to the bottom, followed by <enter> to select the entry in the list) to get to my last message.
• since messages from plugins are also in the timeline, <up><enter> might not get you back to the last message you types: additional keystrokes - and, more importantly, additional time thinking to distinguish plugin messages from actual user messages - might be required in these cases.

I wanted a more ergonomic solution, that would allow me to mindlessly whack one single key to get to the last message that I had actually typed myself, without being distracted from whatever train of though I'd been previously thinking about on expending the mental effort the distinguis plugin-originated messages from actual user-typed messages and navigating to the correct entry: just whack one key and done, without any focus-breaking faffing about selecting from menu items.
