**Presentations** holds the slides for your sessions. You download a
presentation in the browser once, and from then on it is on this screen,
ready to show on the television.

## Getting a presentation onto the computer

1. Click **Browser** and go to wherever the presentation is — your
   email, a shared folder, wherever it was sent to you.
2. Download it the way you normally would.
3. Wait until the download has finished.

That is all. It appears in **Presentations** by itself a few seconds
later. You do not have to save it anywhere special, move it, or open it.

PowerPoint files and PDF files both work.

Your download stays in the browser exactly as it was. Nothing here
changes it, moves it or deletes it.

## Opening the library

Click **Presentations** on the bar.

Each session is a card with its name and a picture of one of its slides.
Find tonight's by looking at the picture.

If a session has only just been downloaded, its card says it is being
got ready. It will be ready in a moment.

## Quick Look — checking the slides first

**Quick Look** lets you read through a session before you show it to
anybody.

* **Next** and **Previous** move through the slides.
* **Back to Presentations** returns to the library.
* **Present** starts the slideshow straight away.

Looking through a session in Quick Look does not count as having
presented it.

## Changing the picture on the card

The first slide of a session is often the same opening slide as every
other session, which makes the cards hard to tell apart. Use the slide
that names the session instead — usually the second one.

1. Click **Quick Look**.
2. Press **Next** until you reach the slide you want.
3. Click **Use this slide as the picture**.

The card changes straight away, and stays that way — after you close the
library, and after the computer is switched off and on again.

Choosing the picture does not change where the slideshow starts. It
always starts at the first slide.

## Showing a presentation

Click **Present**, on the card or inside Quick Look.

The slides fill the whole screen. Nothing else is on it.

| To do this | Press |
| --- | --- |
| Next slide | **Space**, the **right arrow**, the **down arrow** or **Page Down** |
| Previous slide | The **left arrow**, the **up arrow** or **Page Up** |
| First slide | **Home** |
| Last slide | **End** |
| Finish | **Esc** |

A presentation remote works too — the forward and back buttons on the
clicker are the same as Page Down and Page Up.

## Finishing

Press **Esc**.

You come straight back to the library. Going past the last slide does
the same thing.

## Removing a presentation

Click **Remove** on its card, and confirm.

That takes it off this screen. Your download in the browser is not
touched, so you can always get it back by downloading it again.

## Presentations you no longer need

The computer tidies up after itself, so the library does not slowly fill
up with old sessions.

A session you have shown is kept for a month after the last time you
showed it. Showing it again starts that month over.

A session you downloaded but never showed is kept for six months.

You do not have to do anything about this, and nothing disappears while
you are using it.

## If a presentation will not open

Its card says so, and offers only **Remove**. Usually the file did not
download properly.

Download it again. Your original download is still there either way.
