When I use Gmail and Google Docs (with Firefox 3.6.6), I often cut text from another HTML or PDF document.

When I paste this text into the document body, Gmail and Google Docs will paste the text and the formatting. I almost never want to copy the formatting from another document, and I instead need to clean up the formatting afterwards.

Is there a magic key combination so that I can just paste the text, and not the formatting? Can I make this the default behavior for my Gmail or Google Docs editor?

I assume this behavior is mostly within the Google application. I am also assuming that this behavior is common across most Google web apps. If this is actually a web-browser bug feature, let me know.
