<p>By default, Haiku's option key, to invoke commands from menus for example, is not the usual <spanclass="key">CTRL</span> key, but <spanclass="key">ALT</span> instead. This has historical reasons, because the BeOS was inspired somewhat by MacOS. After you get used to it, it actually feels better as e.g. <spanclass="key">ALT</span> <spanclass="key">C</span> and <spanclass="key">ALT</span> <spanclass="key">V</span> is reached more conveniently on the keyboard and these commands seamlessly integrate into the <acronymtitle="Bourne Again Shell">bash</acronym> shell of the Terminal, where <spanclass="key">CTRL</span> <spanclass="key">C</span> quits the running process.</p>
<p>In any case, you can switch to the maybe more familiar <spanclass="key">CTRL</span> key in the <ahref="prefs-keymap.html">Keymap</a> preferences. The user guide will always describes the default configuration with option key being <spanclass="key">ALT</span>.</p>

<p>In a Tracker window, if you just start typing, Tracker scrolls to and selects the file that best fits your incremental search. If there's no file starting with your typed letters, files that contain the search string anywhere in their name or other displayed attributes are selected. This search is <i>not</i> case-sensitive.<br/>
The letters you type appear at the bottom-left, where normally the number of items is listed. After a second it reverts back and you could start a new incremental search.</p>
