GNU Info (emacs)Strict CompletionStrict Completion ----------------- There are three different ways that <RET> can work in completing minibuffers, depending on how the argument will be used. * "Strict" completion is used when it is meaningless to give any argument except one of the known alternatives. For example, when `C-x k' reads the name of a buffer to kill, it is meaningless to give anything but the name of an existing buffer. In strict completion, <RET> refuses to exit if the text in the minibuffer does not complete to an exact match. * "Cautious" completion is similar to strict completion, except that <RET> exits only if the text was an exact match already, not needing completion. If the text is not an exact match, <RET> does not exit, but it does complete the text. If it completes to an exact match, a second <RET> will exit. Cautious completion is used for reading file names for files that must already exist. * "Permissive" completion is used when any string whatever is meaningful, and the list of completion alternatives is just a guide. For example, when `C-x C-f' reads the name of a file to visit, any file name is allowed, in case you want to create a file. In permissive completion, <RET> takes the text in the minibuffer exactly as given, without completing it. The completion commands display a list of all possible completions in a window whenever there is more than one possibility for the very next character. Also, typing `?' explicitly requests such a list. If the list of completions is long, you can scroll it with `C-M-v' (Note: Other Window). automatically generated by info2www version 1.2.2.9 |
