Snippets are small fragments of reusable code which, in all the major text editors, can be defined, organized and associated to key shortcuts.

How to set default programs using update-alternatives on Debian-based distributions
More often than not, on our Linux system, we can find two or more applications of the same type installed: it is typically the case of text editors, but we can also have multiple web browsers, for example.
