Question

This page indicates that Greek letters can be inserted into Emacs by using M-i. However, Emacs 23.2.1 in a Debian Squeeze variant inserts the "tab" character when M-i is pressed. How can I insert Greek letters such α and β in Emacs?

Answer 1

You can use another prefix, like:

(global-set-key (kbd "C-x <ESC> a") "α")
(global-set-key (kbd "C-x <ESC> b") "β")

Or use global-abbrev-table as it’s explained on the page you mentioned.
