Paste Text Without Keeping Its Formatting

When you copy text from some applications, and especially from the web, you tend to copy its formatting, such as the text size, font choice and so on. When you then paste this into other text fields, like in an email, it looks funky or out of place, and can make things hard to read. To paste the text without its original formatting (so it formats in the same way as the rest of what you're pasting into), instead of pressing Command (⌘) +V, press Option+Shift+Command (⌘) +V.
