If you're an active Gmail user, you probably know that you can open
Microsoft Word and Excel attachments from within Gmail and import them
to Google Docs. Gmail also provided a basic View as slideshow option
for PowerPoint attachments.
Today we're improving this feature by making it easier for you to
upload presentations from Gmail and edit them in Google Docs. When you
receive a PowerPoint attachment, simply click the View option to open
and preview the presentation in a new online viewer, powered by Google
Docs. If you'd like to save the presentation to Google Docs, just click
Edit Online and it'll be imported into Google Docs.
To read more about this new viewer, check out the Gmail blog.
