[FEATURE]: Search field with Ctrl+F

[unphased]

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

Opencode runs its TUI inside alternate screen mode and unlike e.g. codex it is not possible to search in the terminal scrollback buffer.

So I suggest we add a feature to obtain this. It's very easy to have some very long running chats in opencode.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: TUI - Search for and find string in session buffer #4714: [FEATURE]: TUI - Search for and find string in session buffer

Both issues request the ability to search within the TUI session buffer, which is the same core functionality. Issue #4714 has additional context about inspirations (vim, tmux, ghostty) that might be useful for implementation.

Feel free to ignore if this doesn't address your specific case.
