# The "Presentation" Tool

The Presentation tool allows you to include and display various documents directly within a session.

The core concept is collaborative work: participants save their files in the shared document storage and make them available to the group. The tool is added via the button in the tool sidebar.

All graphical tools share the same basic operations (drawing, moving, deleting). For more details, please refer to: General Functions of Graphical Tools

# Functions at a Glance

Basic control is handled via tool-specific buttons:

  1. Manage and Select Documents: Opens the file selection dialog.
  2. Navigation (Scrolling): For multi-page documents, you can flip forward and backward. The current page number and total pages are displayed.
  3. Full-Screen Mode: For a full-page display of documents.

# Important Usage Notes

Synchronicity (Scrolling)

All session participants can scroll through the presentation. Please note: a change to the currently displayed page applies to all participants simultaneously. This behavior can be restricted via the session settings.

Drawings on Documents

You can draw directly on documents. These annotations are visible to all participants but are not saved within the document itself. When flipping to the next page, you will be asked whether existing drawings should be deleted or carried over to the next page.

No Direct Editing

Directly editing the content (changing text, etc.) is not possible within the tool. To edit files:

  1. Download the file to your computer.
  2. Edit it locally.
  3. Upload it again or use the Desktop Sharing function.

The folder structure on the left corresponds to your document directory. Clicking a folder displays the files available there on the right. Clicking a document loads it into the tool for all participants.

# Missing Preview Images

If a question_mark question mark is displayed, a preview is not yet available.

This can happen if:

  • The conversion is still in progress. Wait a few seconds and click the refresh Refresh button.
  • The file format is not supported for visual display (e.g., .mp4).
