### Does syntax highlighting work during incremental history search? ### Does syntax highlighting work during incremental history search?
Yes! Highlighting the command line during an incremental history search (by default bound to
to <kbd>Ctrl+R</kbd> in zsh's emacs keymap) requires zsh 5.4 or newer.
If you're using `history-incremental-search-backward` (by default bound to <kbd>Ctrl+R</kbd> Under zsh versions older than 5.4, the zsh-default [underlining][zshzle-Character-Highlighting]
in zsh's emacs keymap) then it works with _zsh version 5.3 and newer_.
If you're using `history-incremental-pattern-search-backward`, then syntax highlighting works
in _zsh 5.3.2 and newer_ due to [a bug in zsh](http://www.zsh.org/cgi-bin/mla/redirect?WORKERNUMBER=40285).
Under zsh 5.2 and older, the zsh-default [underlining][zshzle-Character-Highlighting]
of the matched portion of the buffer remains available, but zsh-syntax-highlighting's of the matched portion of the buffer remains available, but zsh-syntax-highlighting's
additional highlighting is unavailable. (Those versions of zsh do not provide additional highlighting is unavailable. (Those versions of zsh do not provide
enough information to allow computing the highlighting correctly.) enough information to allow computing the highlighting correctly.)
See [issue #288][i288] for details. See issues [#288][i288] and [#415][i415] for details.
