In the lower right corner are the shortcut buttons to change the view (normal, edit, slide show – and reading in PPT 2010), plus the zoom tools.
In my sample I am in the Slide Sorter view:
If I want to edit an individual slide, I select the slide and click the far left button for Normal/Edit view.
But the Slide Sorter button is also a toggle. When in Slide Sorter view, click the slide sorter button again and you change to the Normal view. Click it again and you go back to Slide Sorter.
This works in PPT 2007 and 2010. Not really a time saving shortcut as the buttons are literally next to each other – but it is a little known feature.
