One Tap Code Block is a Chrome extension designed to streamline the process of writing Markdown code blocks for developers. This lightweight tool allows users to easily insert or wrap fenced Markdown code blocks by simply pressing the Right Alt key or the middle mouse button within supported editors. It is particularly useful for those who frequently use platforms like GitHub and ChatGPT for their coding needs.

The extension supports various environments, including textarea editors, contenteditable/rich text editors, GitHub Issue descriptions, and ChatGPT message inputs. However, it intentionally ignores search boxes, single-line input fields, title fields, and non-editable page content. With no required accounts, tracking, or analytics, One Tap Code Block provides a straightforward and efficient solution for Markdown coding without the clutter of external services.
