Syntax: AutoComplete [prefix]
Abbreviation: AC
attempts to extend the prefix using matching words from your
open documents, and inserts the extended text into your document. If the
prefix can be extended unambiguously, the matching text is immediately
inserted into your document. Otherwise, ne displays a
selection of all words in open documents that match prefix, and inserts
the word you select into the current document.
Matching words from the current document display normally; those which only
exist in other open documents are bold and with a trailing asterisk. If no
prefix is given on the command line, or if AutoComplete is
selected from the Extras menu or using a keyboard shortcut, the word
characters to the immediate left of the cursor in the current document are used
as the prefix. Note that if no word characters are to the left of the
cursor, or the prefix given on the command line is an empty string
(""), then all words in all your open documents are displayed. Prefix
matches may be case sensitive or not depending on the current document’s
CaseSearch flag state. See CaseSearch.
