<h3>Leaving comments and replying to them</h3>
<p>To leave a comment to a certain object (text box, shape etc.):</p>
<ol>
<li>select an object where you think there is an error or problem,</li>
switch to the <b>Insert</b> or <b>Collaboration</b> tab of the top toolbar and click the <divclass ="icon icon-comment_toptoolbar"></div><b>Comment</b> button, or<br/>
<p>The object you commented will be marked with the <spanclass="icon icon-added_comment_icon"></span> icon. To view the comment, just click on this icon.</p>
<p>To add a comment to a certain slide, select the slide and use the <spanclass="icon icon-comment_toptoolbar"></span><b>Comment</b> button on the <b>Insert</b> or <b>Collaboration</b> tab of the top toolbar. The added comment will be displayed in the upper left corner of the slide.</p>
<p>To create a presentation-level comment which is not related to a certain object or slide, click the <spanclass="icon icon-commentsicon"></span> icon on the left sidebar to open the <b>Comments</b> panel and use the <b>Add Comment to Document</b> link. The presentation-level comments can be viewed on the <b>Comments</b> panel. Comments related to objects and slides are also available here.</p>
<p>Any other user can answer to the added comment asking questions or reporting on the work they have done. For this purpose, click the <b>Add Reply</b> link situated under the comment, type in your reply text in the entry field and press the <b>Reply</b> button.</p>
<p>If you are using the <b>Strict</b> co-editing mode, new comments added by other users will become visible only after you click the <spanclass="icon icon-saveupdate"></span> icon in the left upper corner of the top toolbar.</p>
<li>by author: <b>Author from A to Z</b> or <b>Author from Z to A</b>.</li>

To open it again, click the <divclass ="icon icon-resolvedicon"></div> icon,</li>
<li>if you want to manage comments in a bunch, open the <b>Resolve</b> drop-down menu on the <b>Collaboration</b> tab. Select one of the options for resolving comments: <b>resolve current comments</b>, <b>resolve my comments</b> or <b>resolve all comments</b> in the presentation.</li>
</ul>
<h3>Adding mentions</h3>
<pclass="note">You can only add mentions to the comments made to the presentation content and not to the presentation itself.</p>
<p>When entering comments, you can use the <b>mentions</b> feature that allows you to attract somebody's attention to the comment and send a notification to the mentioned user via email and <b>Talk</b>.</p>
<p>To add a mention,</p>
<ol>
<li>Enter the "+" or "@" sign anywhere in the comment text - a list of the portal users will open. To simplify the search process, you can start typing a name in the comment field - the user list will change as you type.</li>
<li>Select the necessary person from the list. If the file has not yet been shared with the mentioned user, the <b>Sharing Settings</b> window will open. <b>Read only</b> access type is selected by default. <ahref="https://helpcenter.onlyoffice.com/userguides/groups-guides-documents-share-documents.aspx">Change it if necessary</a>.</li>
<li>Click <b>OK</b>.</li>
</ol>
<p>The mentioned user will receive an email notification that they have been mentioned in a comment. If the file has been shared, the user will also receive a corresponding notification.</p>
<li><b>Remove Current Comments</b> - to remove the currently selected comment. If some replies have been added to the comment, all its replies will be removed as well.</li>
<li><b>Remove My Comments</b> - to remove comments you added without removing comments added by other users. If some replies have been added to your comment, all its replies will be removed as well.</li>
