Snippets and macros have been a part of Komodo since the beginning. Snippets are for inserting frequently-used pieces of boilerplate text into documents. They have some pre-canned functionality in their shortcuts, but can't be extended.
Coding is fun, but typing is work. Komodo IDE provides several features that let you do less typing so you can have more fun.
The most obvious keystroke-saving feature is autocomplete, but Komodo also has a method for inserting snippets of code by typing their name in the buffer. We call this feature Abbreviations.
