Open up Microsoft Power Point and find the presentation you are currently working on.
Click anywhere in your presentation to open up a text box and click where you want to insert the link.
Find the tab "insert" on the top window. This opens up a new frame with different options. Choose the one called "Hyperlink."
Write the text you wish to display for the link under "text" in the window that opens. On the bottom of this window where it says "address," put in the web address or site you are linking to. Click "OK" to insert this hyperlink into your presentation.
