I copy and paste text constantly. And a lot of that text is formatted, meaning that it is colored, or bolded, or size 34, or an odd font etc. 99% of the time I want to paste the text only but a lot of text editors will retain the style information, or worse, retain unseen artifacts that will mess up a page’s formatting. One way to remove the style information is to paste text into Notepad and copy it again to remove the styling. The better way is to use these two keyboard shortcuts to remove the style information entirely:

select text and press control+spacebar
This has worked in every application I have tried so far (e.g. Word 2010, Gmail, Google sites etc.)

control+shift+v
Pastes text without the style (doesn’t work in every program, such as Word which is shift enables for other shortcuts)
