# Collaborative Presentation Editing

Presentation Editor offers you the possibility to work at a presentation collaboratively with other users. This feature includes:

- simultaneous multi-user access to the edited presentation
- visual indication of objects that are being edited by other users
- synchronization of changes with one button click
- chat to share ideas concerning particular presentation parts
- comments containing the description of a task or problem that should be solved

### Co-editing

Presentation Editor allows to select one of the two available co-editing modes. Fast is used by default and shows the changes made by other users in realtime. Strict is selected to hide other user changes until you click the Save icon to save your own changes and accept the changes made by others. The mode can be selected in the Advanced Settings.

When a presentation is being edited by several users simultaneously in the Strict mode, the edited objects (autoshapes, text objects, tables, images, charts) are marked with dashed lines of different colors. The object that you are editing is surrounded by the green dashed line. Red dashed lines indicate that objects are being edited by other users. By hovering the mouse cursor over one of the edited passages, the name of the user who is editing it at the moment is displayed. The Fast mode will show the actions and the names of the co-editors once they are editing the text.

The number of users who are working at the current presentation is specified in the left lower corner at the status bar - . If you want to see who exactly are editing the file now, you can open the Chat panel with the full list of the users.

Click this icon to manage the access to the file; this can be done both when there are no other users who view or co-edit the document at the moment and when there are other users and the icon looks like .

The updates will be highlighted for you to check what exactly has been changed.
