When using Google Chrome, you can copy slides from one presentation to another, bring shapes from drawings into a slide, or even take tables from a spreadsheet and paste it into a Gmail message -- and formatting stays exactly the same. You can access copy/paste using keyboard shortcuts or from the right-click menu.
If you're interested in sending information from a Google Spreadsheet, this can cut down on time, compared to your recipient having to open a Spreadsheet. I recommend using this in instances when you're sharing just a few cells, rather than data from an entire Spreadsheet.
The best way to take advantage of this new update is by using the basic copy / paste keyboard shortcuts:
To Copy – CTRL (command for Macs) + C
To Paste – CTRL (command for Macs) + V
On a different browser? Try the web clipboard which will also help you copy and paste: http://goo.gl/WZxKH
