For mobile devices, it’s even more valuable. Typing text on a tiny device is no fun; if a user
needs to enter a long string of letters, appropriate Autocompletion can save her a great deal
of time and frustration. Again, email addresses and URLs are excellent candidates, to support
mobile email and web usage.
Autocompletion is also common in text editors and command-line UIs. As users type commands
or phrases, the application or shell might offer suggestions for completion. Code
editors and OS shells are well suited for this, because the language used is limited and predictable
(as opposed to a human language, such as English); it’s therefore easier to guess
what the user tries to type.
Finally, lists of possible autocompletions can serve as a map or guide to a large world of
content. Search engines and site-wide search boxes do this well—when the user types the
beginning of a phrase, an Autocompletion drop down shows likely completions that other
people have typed (or that refer to available content). Thus, small corrections and gentle
guidance are provided to a curious or uncertain user, and they offer a way to navigate a
small corner of the public mental landscape
