However, if a shortcut key ('W' for Windows) is pressed, that system will boot. If any other key is pressed, the menu will show with no timeout.</td>

<td><tt>screensaver</tt></td>
<td>Tells rEFInd what methods to use to locate boot loaders. The <tt>internal</tt>, <tt>external</tt>, and <tt>optical</tt> parameters tell rEFInd to scan for EFI boot loaders on internal, external, and optical (CD, DVD, and Blu-ray) devices, respectively. The <tt>hdbios</tt>, <tt>biosexternal</tt>, and <tt>cd</tt> parameters are similar, but scan for BIOS boot loaders. (Note that the BIOS options scan more thoroughly and actively on Macs than on UEFI-based PCs; for the latter, only options in the firmware's boot list are scanned, as described on the <a href="using.html">Using rEFInd</a> page.) The <tt>manual</tt> parameter tells rEFInd to scan the configuration file for manual settings. You can specify multiple parameters to have the program scan for multiple boot loader types. When you do so, the order determines the order in which the boot loaders appear in the menu. The default is <tt>internal, external, optical, manual</tt> on most systems, but <tt>internal, hdbios, external, biosexternal, optical, cd, manual</tt> on Macs.</td>

<td>Tells rEFInd how aggressively to scan for BIOS/CSM/legacy boot loaders on UEFI-based PCs. Ordinarily or if this option is set to <tt>false</tt>, <tt>off</tt>, or <tt>0</tt>, rEFInd presents only those options that were available in the NVRAM when it launched. When uncommented with no option or with <tt>true</tt>, <tt>on</tt>, or <tt>1</tt> set, rEFInd adds every possible BIOS-mode boot device (of types specified by <tt>scanfor</tt>) as a BIOS/CSM/legacy boot option. This latter behavior is sometimes required to detect USB flash drives or hard disks beyond the first one.</td>

<td><tt>default_selection</tt></td>
<td>a substring of a boot loader's title, or a numeric position; optionally followed by two times in <tt class="variable">HH:MM</tt> format</td>
- <td>Sets the default boot OS based on the loader's title, which appears in the main menu beneath the icons when you select the loader. You can enter any substring of the title as the <tt>default_selection</tt>, so long as it's two or more characters in length. It's best to use a unique substring, since rEFInd stops searching when it finds the first match. Because rEFInd sorts entries within a directory in descending order by file modification time, if you specify a directory (or volume name, for loaders in a partition's root directory) as the <tt>default_selection</tt>, the most recent loader in that directory will be the default. One-character entries are matched against the first character of the title, except for digits, which refer to the numeric order of the boot loader entries. If you specify a comma-delimited list of names <i><b>in quotation marks,</b></i> rEFInd will search on these in turn until it finds a match. For instance, <tt>default_selection "alpha,beta"</tt> will launch <tt>alpha</tt> if it's available, and <tt>beta</tt> if <tt>alpha</tt> is not available but <tt>beta</tt> is. You may optionally follow the match string by two times, in 24-hour format, in which case the entry applies only between those two times. For instance, <tt>default_selection Safety 1:30 2:30</tt> boots the entry called <tt>Safety</tt> by default between the hours of 1:30 and 2:30. These times are specified in whatever format the motherboard clock uses (local time or UTC). If the first value is larger than the second, as in <tt>23:00 1:00</tt>, it is interpreted as crossing midnight—11:00 PM to 1:00 AM in this example. The last <tt>default_selection</tt> setting takes precedence over preceding ones <i>if</i> the time value matches. Thus, you can set a main <tt>default_selection</tt> without a time specification and then set one or more others to override the main setting at specific times.</td>
