CotEditor is a text editor designed for editing plain text files from programming to daily note-taking. CotEditor offers a lot of useful features that are not available in the macOS’s TextEdit.
Powerful find and replace
The CotEditor's find & replace feature not only supports the regular expression but also displays a list of search results, or highlights matched words in your document.
Capture the document structure by syntax highlighting
CotEditor colorizes particular strings such as reserved words of programming languages, TeX commands, and HTML elements to make the document's structure easy to understand.
Quick overview of the document's outline
CotEditor’s Outline extracts predefined keywords from the document and displays them in a drop-down menu. By clicking on a listed item, you can go directly to the corresponding part of your document.
Scripting for text editing automation
The Script menu lets you run scripts to manipulate your document or launch external programs.
