I now know that I could have closed the Find window, at which point “Undo Replace All” would have appeared as an option under the Edit menu. But the file was auto-saved with the unintentional change. I could not figure out how to undo my change, so I closed the main window thinking that I had not saved my file. I did a Find to search for text, but instead of hitting “Find All”, I hit “Replace All” by mistake. (1) I think the 'Enable Auto Save with Versions” feature is a bit dangerous. However, I am giving it 4 stars instead of 5 for two reasons: I love the clean, simple interface and especially the speed with which it launches. This is the fastest editor I have seen for working with small text files. Character inspector that shows the zoomed glyph and Unicode information.Auto-generated outline menu for fast navigation.Handling file encoding and line endings with care.Auto-backup with/without overwriting actual document files.Powerful find and replace with the regular expression.Syntax highlighting including more than 50 preset languages.You can also easily write your own macro in your favorite languages. There are, of course, syntax highlighting for various languages, find and replace with the regular expression, auto-indentation, command-line tool, and lots of other deep functions. However, at the same time, CotEditor is neither software only for beginners nor a typical minimal “zen-style” editor. The simply organized user interface doesn't disturb your task. It's perfect for you to write a draft version of your document or a scratch code.

There are no complicated setting files that require geek knowledge so that you can access all your settings including syntax definitions and themes from a standard settings window.ĬotEditor launches so quickly that you can write your text immediately when you want to.

It means, you already know how to use it even on the first launch. CotEditor looks and behaves just as macOS applications should. The application is exactly made for macOS. CotEditor is a light-weight, neat, yet powerful text editor designed for editing plain-text files such as web pages (HTML, CSS), program source codes (Python, Ruby, Perl, etc.), structured texts (Markdown, Textile, TeX, etc.), or any other kind of plain-text.
