The Newsfeed feature in SharePoint 2013 is a fast and easy way to convey short, informative updates to other users in your organization. You can share your updates with everyone that has access to your feed, or with specific people or sites that you follow. You can interact with other users within your posts in the Newsfeed in a variety of ways.

You can use tags which are keywords that help users easily sort pertinent information from posts. Trending tags will appear in the right pane of your Newsfeed. To add a tag to your post, you simply enter the pound sign and a word that you wish to use as a tag. As you do this, commonly used tag suggestions will appear under the box.

Mentioning is another way to connect with other users. Mentioning inserts a shortcut to the About Me page of the user you have mentioned. The user also receives a notification that they have been mentioned by you in a post. To mention a user, enter an ampersand (@) character before the users name and select from the list of the available users.

You can also follow another users Newsfeed so that their status updates appear on your page.

A stable internet connection isn’t always available, but sometimes work still needs to get done. Offline editing allows you to make changes to your files no matter what the state of your wireless. Google will sync any offline changes made as soon as a connection is found.

In order to use offline editing, you will need to have the Chrome browser, or a Chrome OS device. Start by downloading the Google Drive for your PC. The link can be found at the bottom of the Drive menu on the left. Follow the instructions to complete the installation.

To enable offline access on your computer, navigate to the My Drive main page. Click “More” on the left-hand side of the screen. Select “Offline Docs”, then click the “Enable offline” button.

You can also view non drive files such as PDFs, Microsoft Office files, and images, from your Google Drive folder, even when you're disconnected from the Internet.

The presenter mode in PowerPoint 2013 got a much needed overhaul. The interface has been updated with the same Windows 8 look and feel as PowerPoint. Microsoft takes the Metro style design one step further by making the default color much darker, so that the light from your presentation screen won’t distract your viewers. 

If you are having trouble reading your presentation notes, you can increase the size of the note text with one simple click. Now you can step out from behind the presenting computer and your notes can be easily read from a distance.

A new slide navigation grid allows you to move to any slide in the presentation. You can use it to skip to any part of a presentation without scrolling through the entire thing. This feature will allow you to have optional slides that you can use only if needed, such as slides that answer specific questions from viewers.  

One of the best new features is the Zoom function. Presenter mode will allow you to select an element of any slide to showcase. For example: A slide contains an important chart you wish to go over in detail. Simply click the Zoom icon, select the chart, and PowerPoint will zoom in and show just the chart. Click again to return seamlessly to the slide and continue your presentation.

Excel has always had a variety of data analysis features, but they were sometimes hard to find or not easily understandable. Quick Analysis takes all those features and brings them together in an easy to use format.

Whenever you select data the Quick Analysis button appears near the bottom right of the selection.  Clicking the button brings up a gallery of options. By default the Formatting gallery is visible, but the tab bar will allow you to navigate to the Charts, Totals, Tables, and Sparkline’s galleries. Just hover your mouse over any option to see exactly what your data will look like.

The new Quick Analysis feature allows fear-free exploration of Excel’s analytical capabilities. It lets you experiment with new ways to showcase your data without reaching for the undo button.
