Selection Highlighter

Highlight occurrences of selected text, with or without a keypress.

▶

Selection Highlighter is a powerful Chrome extension designed for effortless text inspection and keyword analysis across various websites like GitHub, StackOverflow, Reddit, and more. It lets users highlight all occurrences of selected text automatically or upon a configurable keypress, eliminating the need for manual searches with CMD+F.

With customizable JavaScript options, users can enable features such as matching whole words, case-insensitive search, and blacklisting certain sites or HTML nodes to refine highlights. Being open source, it promotes transparency and further customization by allowing users to explore and modify its code directly through the Chrome Dev Console. This extension is ideal for developers, researchers, and anyone who frequently inspects code or documents online.

Pros

Simple and easy to use; works by double clicking a word to highlight all occurrences on the page.
Improves productivity and is a real time saver when reviewing or editing text.
Customizable options such as color and regex support, which allow personalization.
Developer transparency and open source code availability appreciated by users.
Works well for code review and generally reliable for highlighting tasks.

Cons

Does not work well or at all on certain platforms such as Google Docs or Microsoft Docs code snippets.
Highlighted words disappear with one click; users want a way to keep highlights fixed until manually cleared.
Does not support highlighting of symbols or special characters like * or +.
No built-in multi-highlight feature that allows multiple words to be highlighted simultaneously with distinct colors.

Very good! 💪🏼

It kind of works, but the annoying thing is that it doesn't function for symbols. So searching something like * or + alone won't work...and guess what I needed this for. :')

Отличное расширение. Работает как и должно. Выделяет от одного символа до целого предложения.
