FAQ
Frequently Asked Questions
It is often humorously called an operating system because it is so extensible and can perform so many functions (email, news, games, etc.), but technically it is an application that runs on an OS.
It originally stood for 'Editor MACroS' for the TECO editor. The name was retained for later, more powerful versions.
It has a notoriously steep initial learning curve due to its unique keybindings and vast functionality, but many users find the long-term efficiency gains to be worth it.
The main historical and cultural rival is the vi editor (and its enhanced version, Vim). The choice between them is a classic and often light-hearted debate among programmers.
