 If auto completion is turned off, you can manually force the completion of what you've typed, limiting the selection to either the list of functions or the list of words. By default, these functions are bound to <kbd>Ctrl+Space</kbd> (functions) or <kbd>Ctrl+Enter</kbd> (words); they are also available in the [Edit menu](../editing/#edit-menu). Typing one of these keystrokes or using those menu commands attempts an immediate completion: if there is a single matching entry in the wordlist, that entry is used, with no display of a list. If there are multiple matching entries, the list is displayed just as if auto-completion were triggered at the same point.
 
-Note: Manual "Function completion" (currently) shows a list of all the functions in the wordlist, even if they don't match the current prefix—unless no function matches the prefix, in which case no list is shown. Manual "Word completion" shows only the matching words.

 ### Displayed Completion List
 
-When you use [Manual Completion](#manual-completion), the list will only show the items that were manually triggered -- so either only the word list or only the function list.  If [Automatic completion](#automatic-completion) is triggered, the list will show both words and functions that match.  As of v8.3.1, the completion list will use the <i>fx</i> icon to help the user tell the difference between the "[Function completion](#function-completion)" items (keywords and functions from the configuration file will get the <i>fx</i> icon) and "[Word completion](#word-completion)" items (words from the active document will _not_ have the icon).
