Multi-language file support
Correct syntax coloring of multi-language files and templated files, common in many web programming frameworks. Add custom language support (User-Defined Languages or UDL, used to provide support for RHTML, Template-Toolkit, HTML-Mason, Smarty and Django).

Standard editing features
Code commenting, auto-indent and outdent, block selection, incremental search, reflow paragraph, join lines, enter next character as raw literal, repeat next keystroke and clean line endings on "save".

Syntax checking
Instant feedback for all fully-supported languages.

Syntax coloring
Spot errors easily and improve readability and context, even in multi-language files (unique to Komodo!).

Vi emulation
Modal Vi keybindings emulate navigation, text insertion and command behavior. Custom commands can be implemented by adding Komodo macros to a Vi Commands Toolbox folder.

Emacs keybindings
Emacs-like keybinding scheme supports new editor features modeled on Emacs, such as transient marks (similar to the Emacs "mark ring"), repeat next command and reflow paragraph.

HTML preview
Check HTML, XML and CSS files side-by-side or in a browser, using arbitrary files or URLs.

Multilingual Input Method Editor (IME) support
Use your standard keyboard to enter multi-byte characters, such as Simplified Chinese, Japanese and Korean.

Code snippets
Store any piece of code for reuse.
