Vim Compose is a browser extension that allows you to use the powerful vim text editor to compose and edit text in input fields on the web. Developed by Martin Bidlingmaier, this free add-on is available for the Chrome platform.

With Vim Compose, you can easily open the vim editor within your browser by focusing on an input field and pressing Ctrl-Shift-E or clicking the extension button in the toolbar. This enables you to take advantage of vim's extensive features and functionality while composing emails, writing documents, or editing any text on the web.

One of the key benefits of Vim Compose is its support for markdown formatting. If the input field supports formatted text, you can use markdown syntax to format your text in vim. This allows you to create well-structured and visually appealing content directly within your browser.
