 ## Unreleased
 
+### Added
+- Copy mode now supports literal smart-case search with `/` and `?`, repeating with `n` and `N`, match highlighting, and tmux-style cross-line `w`/`b`/`e` word motions. (#1230)
+
 ### Fixed
 - `herdr --remote` now installs remote helper binaries without routing the binary stream through a multiline `/bin/sh -c` command, fixing installs for non-POSIX login shells such as xonsh. (#1203, thanks @nhumrich)

 **Update and restore.** `herdr update` installs a new binary, but a running server keeps using the old process until it is stopped or handed off. Stop the old server to use the new version. Stopping exits pane processes. Run `herdr server stop`, then run `herdr` again for the default session. For a named session, run `herdr session stop <name>`, then run `herdr session attach <name>` again. `herdr update --handoff` is experimental and tries to move live panes, including foreground processes such as dev servers, from the old server to the new one. With current official integrations installed, supported agent panes can restart from their native agent sessions after a server restart or update.

 ## Copy mode
 
-Press `prefix+[` to enter copy mode for the focused pane. Use `h/j/k/l`, `w/b/e`, `{`/`}`, `PageUp`/`PageDown`, `ctrl+b`/`ctrl+f`, and `ctrl+u`/`ctrl+d` to move, `v` or Space to start a selection, `y` or Enter to copy it, and `q` or Esc to leave without copying. The configured prefix keeps its normal meaning in copy mode; with the default prefix, `ctrl+b` enters prefix mode instead of paging up, so use a different prefix if you want `ctrl+b` for copy-mode page-up. Mouse drag-select copies without entering copy mode at all.

Press `/` or `?` for forward or backward literal search, then `n` or `N` to repeat in the same or opposite direction. Search is case-insensitive unless the query contains an uppercase letter. Use `v` or Space to start a selection, `y` or Enter to copy it, and `q` or Esc to leave without copying. Esc clears an active selection or search before exiting. Copy mode does not pause the pane process: output remains live, follows at the bottom, and stays pinned when you navigate into history.
