This is the home page for “xmsi-mode” 〔xmsi-math-symbols-input.el〕. It is a Emacs minor mode for inputing math symbols or common Unicode characters.
Call “xmsi-mode” to turn the mode on. Call it again to turn off.
Type “inf”, then press 【Shift+Space】, then it becomes “∞”. Here's sample abbrev:
| abbrev | symbol |
|---|---|
| a | α |
| b | β |
| p | π |
| l | λ |
| g | γ |
| G | Γ |
| sum | ∑ |
| prod | ∏ |
| c+ | ⊕ |
| rt | √ |
| and | ∧ |
| != | ≠ |
| >= | ≥ |
| => | ⇒ |
| -> | → |
| e' | é |
| e` | è |
| e" | ë |
| e^ | ê |
| n~ | ñ |
| dsR | ℝ |
| deg | ° |
| ^2 | ² |
| _i | ᵢ |
The abbreviations are based on HTML/XML entity names and Mathematica's 【Esc abbrev Esc】.
If you have a text selection, then selected word will be taken as input. For example, type sin(a), select the “a”, then press 【Shift+Space】, then it becomse sin(α).
To see the full list of supported chars and their abbrevs, call “xmsi-list-math-symbols”.
Here's a list of chars the mode suports. (for the complete up-to-date list, call “xmsi-list-math-symbols”.)

The mode currently supports over 500+ math symbols by abbrev input. (Any other char in unicode can be entered by decimal or hexadecimal or by name.)
All XML char entity abbrevs are supported. For example, copy becomes “©”.
(See: HTML/XML Entities (Character/Unicode/Symbol) List)
To type any unicode by its code point in decimal, use “&#n;”. For example, α becomes “α”.
Ending semicolon “;” is optional.
To type any unicode by hexadecimal, use &#x‹number›;. For example, α becomes α.
Ending semicolon “;” is optional.
To type any unicode by the char's unicode full name, type 【Ctrl+x 8 Enter】 (ucs-insert). Asterisk “*” can be used as a wildcard to find the char. For example, calling “ucs-insert”, then type *arrow then Tab, then emacs will list all unicode char names that has “arrow” in it. (this feature is part of Emacs 23)
For best result, you'll need a font that support unicode. See: Best Fonts for Unicode.
Also, you should be using Emacs 23, because it has a new unicode engine and font engine that supports operating system's fonts.
Download the mode for $5. Use the paypal button below. In the comment field, put “emacs math symbol input mode”. I'll email you the download link. Make sure your email address is included and correct.
