Screen Sharing
Lync 2013 has a variety of features that allow you to visually interact with your contacts. One method of communicating visually is by screen-sharing, or allowing a contact to visually see what is occurring on your screen(s). Lync allows you to share either specific monitors with your contact, or to give them full view of all screens you may be using. Navigate to a contact or enter their name into the "Find Someone" field. A chat window will open up once the name has been selected presenting you with a variety of options.

The fourth button in the row along the bottom of the window presents you with various forms of visual communication between chat users. To share the view of your screen(s) you will need to select either "All Monitors", "Primary Monitor", or "Secondary Monitor". If you are using a computer setup with multiple monitors, selecting the "Primary" or Secondary Monitor" options will designate individual screens for view to be streamed without the other monitor(s) being shared. Selecting "All Monitors" will give recipients full view of all screens in your computer setup. The "Program" option will actually share control of opened applications with recipient users. For example, if you were working on a Microsoft Word document and wanted somebody to edit it, you could share your document through the "Program" option which would give control of your application over to the other party, where they could then make changes, without having to go through emailing them the file and work on it asynchronously.
Whiteboard and Powerpoint sharing
Setting up video meetings and displaying information to participants through various software features such as PowerPoint and whiteboard presentations are all within reach. Powerpoint, Whiteboard, and Poll are all tools you can use to share visual ideas and content through chat with other users.

Here is an example of how to use the Whiteboard tool with other users. The open space is the "whiteboard" which you can place drawings, pictures, and ideas fore others to see and modify in real-time. There are a number of tools at your disposal such as the marker, highlighter, text-tool, check-marker, and image-uploader. The dot tool can be used as shown above in the picture. The name of the person using the dot tool will be displayed so onlookers may see who is moving the cursor and creating the document changes. Off to the left, you can see the familiar features from the IM window; Multiple participants, connections log, and multi-user IM window all present, making communication both visually and textually simple.
