PowerPoint slide sorter / editor keyboard shortcut
With PowerPoint 2010, you can do Alt + W then:
- I to go to the slide sorter
- L to go back to the normal view
You could also add the slide sorter and normal view to the "quick access toolbar", and then access them with Alt + 3, Alt + 4 (depends on the order of the toolbar).
Pressing CTRL+S in "Slide Show" mode will bring up a modal window with the list of slides. You can then select the slide you wish to jump to. Pressing F1 in "Slide Show" mode will bring up a modal window with the list of shortcuts (including this one). I hope this helps.
Alt+5 in PowerPoint 2010 will switch you from Normal to Slide Sorter View and back again.
