Different ways exist to start a slide show. Once a slide show is running, you can take control pressing keys or clicking the mouse buttons.
By default, a slide show always starts with the first slide. You advance manually through slides up to the last slide. You can change these settings.
Press \<item type=\"keycode\"\>F5\</item\> to run the show.
If you want all shows to start from the current slide instead of the first slide, choose LibreOffice - PreferencesTools - Options - LibreOffice Impress - General and click Always with current page.
Click to advance to the next effect or to the next slide.
Press \<item type=\"keycode\"\>Esc\</item\> to abort the show before the end.
Many more keys are available to control a slide show. You can also right-click to open a context menu with useful commands.
For an automatic change to the next slide, you must assign a slide transition to each slide.
Open the Slide Transition sidebar deck.
In the \<emph\>Advance slide\</emph\> area, click \<emph\>Automatically after\</emph\>, and select a time duration.
Click \<emph\>Apply to All Slides\</emph\>.
You can assign a different time for every slide to advance to the next slide. The rehearse timings feature can assist you to get the timing right.
To advance to the first slide, after all slides have been shown, you must set the slide show to repeat automatically.
Choose \<emph\>Slide Show - Slide Show Settings\</emph\>.
In the Type area, click \<emph\>Auto\</emph\> and select a pause time between shows.
You can start LibreOffice from a command prompt, followed by the parameter \<item type=\"literal\"\>-show\</item\> and an Impress filename. For example, to start the file \<item type=\"literal\"\>filename.odp\</item\> from the command prompt, enter the following command:
\<item type=\"literal\"\>soffice -show filename.odp\</item\>
This assumes that soffice is in the program path of your system, and that \<item type=\"literal\"\>filename.odp\</item\> is located in the current directory.
