Every file that you open +is loaded into its own buffer. Furthermore, Emacs has several special buffers, which do +not contain a file but are used for other things. Such special buffers usually have a +name that starts and ends with an asterisk. For example, the buffer that Emacs shows when +it is first started, is the so-called *scratch* buffer. In the *scratch* buffer, you can +type text in the normal way, but text that is typed there is not saved when Emacs is +closed.</p> + +<p>There is one other special buffer you need to know about, and that is the minibuffer. +This buffer consists of only one line, and is always on the screen: it is the very last +line of the Emacs window, below the status bar for the current buffer. The minibuffer is +where Emacs shows messages for the user, and it is also the place where commands that +require some user input are executed. For example, when you open a file, Emacs will ask +for its name in the minibuffer.</p> + +<p>Switching from one buffer to another can be done with the command <b +class="KEYCAP">C</b>-<b class="KEYCAP">x</b> <b class="KEYCAP">b</b>. This will prompt +you for the name of a buffer (a buffer's name is usually the name of the file you are +editing in it), and it gives a default choice, which is normally the buffer that you were +in before you switched to or created the current buffer. Just hitting <span +class="emphasis"><i class="EMPHASIS">Enter</i></span> will switch to that default +buffer.</p> + +<p>If you want to switch to another buffer than the default offered by Emacs, just type +its name. Note that you can use so-called <b class="KEYCAP">Tab</b>-completion here: type +the first few letters of the buffer's name and hit <b class="KEYCAP">Tab</b>; Emacs will +then complete the name of the buffer. <b class="KEYCAP">Tab</b> completion works +everywhere in Emacs where it makes sense.</p> + +<p>You can get a list of open buffers by hitting <b class="KEYCAP">C</b>-<b +class="KEYCAP">x</b> <b class="KEYCAP">C</b>-<b class="KEYCAP">b</b>. This command will +usually split the screen in two, displaying the buffer you were working in in the top +half, and a new buffer called *Buffer List* in the bottom half. This buffer contains a +list of all the buffers, their sizes and modes, and the files, if any, that those buffers +are visiting (as it is called in Emacs). You can get rid of this split screen by typing +<b class="KEYCAP">C</b>-<b class="KEYCAP">x</b> <b class="KEYCAP">1</b>.</p> + +<div class="NOTE"> +<table class="NOTE" width="100%" border="0"> +<tr> +<td width="25" align="CENTER" valign="TOP"><img src="./imagelib/admon/note.png" +hspace="5" alt="Note" /></td> +<td align="LEFT" valign="TOP"> +<p>Under X, the list of buffers is also available in the Buffer menu in the menu bar.</p> +</td> +</tr> +</table> +</div> +</div> + +<div class="NAVFOOTER"> +<hr align="LEFT" width="100%" /> +<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" +cellspacing="0"> +<tr> +<td width="33%" align="left" valign="top"><a href="emacs.html" +accesskey="P">Prev</a></td> +<td width="34%" align="center" valign="top"><a href="index.html" +accesskey="H">Home</a></td> +<td width="33%" align="right" valign="top"><a href="emacs-modes.html" +accesskey="N">Next</a></td> +</tr> + +<tr> +<td width="33%" align="left" valign="top">Emacs</td> +<td width="34%" align="center" valign="top"><a href="emacs.html" +accesskey="U">Up</a></td> +<td width="33%" align="right" valign="top">Modes</td> +</tr> +</table> +</div> +</body> +</html> + |
