Each bookmarklet highlights its keyword in any open browser tab and scrolls that page to the n_th occurence when clicked n times.
An extra bookmarklet with a black triangle ▲ scrolls upwards to the previous occurence of the current search term
The bookmarklet with half a square ◧ toggles between exact and partial match ("new" matches "news")
Preconfigured for Google, Bing, Duckduckgo, Yandex. See options.
Note: Highlighting won't work on pages where Content Security Policy (CSP) blocks bookmarklets in general (e.g. news.google and yandex .com).
