PowerPoint Shortcut Keys
Keyboard shortcuts in PowerPoint are extremely useful, just like playing computer games. If you have ever seen gaming experts playing computer games, you will probably see them manipulating with the keyboard more than the mouse. Getting familiar with the shortcut keys is another way of achieving efficiency. Most importantly, you do not need to spend time with frustrating steps such as right clicking on a textbox and select copy, then right clicking on the slide and select paste to make a duplicate of the textbox. If you are good with shortcut keys such as Ctrl-D, you just need one step to duplicate the textbox. You do not need to be a professional typist. The only requirement is to be familiar with where the keys are. Here's a link from BetterSolutions.com which shows you a list of PowerPoint shortcut keys. No doubt that the list is long. But remembering one or two will certainly be helpful to you when creating a presentation.
