<li>By default, the <b>Fast</b> mode is selected, the users who take part in the presentation co-editing, will see the changes in real time once they are made by other users.</li>
<li>If you prefer not to see the changes made by other users (so that they will not disturb you, or for some other reason), select the <b>Strict</b> mode, and all the changes will be shown only after you click the <b>Save</b><imgalt="Save icon"src="../images/saveupdate.png"/> icon with a notification that there are some changes made by other users.</li>
<li><b>Default Zoom Value</b> is used to set the default zoom value selecting it in the list of available options from 50% to 200%. You can also choose the <b>Fit to Slide</b> or <b>Fit to Width</b> option.</li>
<b>Default cache mode</b> - used to select the cache mode for the font characters. It’s not recommended to switch it off without any reason. It can be helpful in some cases only, for example, when the Google Chrome browser has problems with the enabled hardware acceleration.
<p>The Presentation Editor has two cache modes:</p>
<li>In the <b>first cache mode</b>, each letter is cached as a separate picture.</li>
<li>In the <b>second cache mode</b>, a picture of a certain size is selected where letters are placed dynamically and a mechanism of allocating/removing memory in this picture is also implemented. If there is not enough memory, a second picture is created, etc.</li>
</ol>
<p>The <b>Default cache mode</b> setting applies two above mentioned cache modes separately for different browsers:</p>
<li>When the <b>Default cache mode</b> setting is enabled, Internet Explorer (v. 9, 10, 11) uses the <b>second cache mode</b>, other browsers use the <b>first cache mode</b>.</li>
<li>When the <b>Default cache mode</b> setting is disabled, Internet Explorer (v. 9, 10, 11) uses the <b>first cache mode</b>, other browsers use the <b>second cache mode</b>.</li>
<li><b>Unit of Measurement</b> is used to specify what units are used on the rulers and in properties windows for measuring elements parameters such as width, height, spacing, margins, etc. You can select the <b>Centimeter</b>, <b>Point</b>, or <b>Inch</b> option.</li>
