Mon Apr 25 13:37:00 UTC 2011 Slackware 13.37 x86_64 stable is released! Thanks to everyone who pitched in on this release: the Slackware team, the folks producing upstream code, and linuxquestions.org for providing a great forum for collaboration and testing. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. As always, thanks to the Slackware community for testing, suggestions, and feedback. :-) Have fun!

<p>When you have opened a file, you can of course move around in it with the cursor. The
|
|
<b class="KEYCAP">cursor keys</b> and <b class="KEYCAP">PgUp</b>, <b
|
|
class="KEYCAP">PgDn</b> do what you'd expect. <b class="KEYCAP">Home</b> and <b
|
|
class="KEYCAP">End</b> jump to the beginning and end of the line. (In older versions,
|
|
they would actually jump to the beginning and end of the buffer.) However, there are also
|
|
<b class="KEYCAP">Control</b> and <b class="KEYCAP">Meta</b> (<b class="KEYCAP">Alt</b>)
|
|
key combos that move the cursor around. Because you do not need to move your hands to
|
|
another part of the keyboard for these, they are much quicker once you get used to them.
|
|
The most important such commands are listed in <a
|
|
href="emacs-basic-editing.html#TABLE-EMACS-BASIC-EDITING">Table 17-1</a>.</p>

<p>Note that many <b class="KEYCAP">Meta</b> commands are parallel to the <b
|
|
class="KEYCAP">Control</b> commands except that they operate on larger units: while <b
|
|
class="KEYCAP">C</b>-<b class="KEYCAP">f</b> goes forward one character, <b
|
|
class="KEYCAP">M</b>-<b class="KEYCAP">f</b> goes forward an entire word, etc.</p>
|
|
|
|
<p>Also note that <b class="KEYCAP">M</b>-<b class="KEYCAP"><</b> and <b
|
|
class="KEYCAP">M</b>-<b class="KEYCAP">></b> require you to type <b
|
|
class="KEYCAP">Shift</b>+<b class="KEYCAP">Alt</b>+<b class="KEYCAP">comma</b> and <b
|
|
class="KEYCAP">Shift</b>+<b class="KEYCAP">Alt</b>+<b class="KEYCAP">dot</b>
|
|
respectively, since <b class="KEYCAP"><</b> and <b class="KEYCAP">></b> are on <b
|
|
class="KEYCAP">Shift</b>+<b class="KEYCAP">comma</b> and <b class="KEYCAP">Shift</b>+<b
|
|
class="KEYCAP">dot</b>. (Unless of course you have a different keyboard layout from the
|
|
standard US layout.)</p>
|
|
|
|
<p>Note that <b class="KEYCAP">C</b>-<b class="KEYCAP">k</b> deletes (kills, as it is
|
|
commonly called) all the text after the cursor to the end of the line, but doesn't delete
|
|
the line itself (i.e., it doesn't delete the final newline). It only deletes the line if
|
|
there was no text after the cursor. In other words, in order to delete a complete line,
|
|
you have to put the cursor at the beginning of the line, and then hit <b
|
|
class="KEYCAP">C</b>-<b class="KEYCAP">k</b> twice: once to delete the text on the line,
|
|
once to delete the line itself.</p>
