Select and Convert to Markdown is a free chrome extension for copying selected text and converting it to markdown code. It has a copy button in its browser's status bar that supports both paste and select.

This is a handy tool for students and for people who write on the web for a living. It supports copy and paste. If you right click on a selection or text area, you can convert it into Markdown code that can be pasted or copied and saved. This means you don't have to worry about copying text again. It also helps you save time because you can paste from clipboard directly into a file.
