Unformat Clipboard solves a wildly known problem with copy and paste on the Mac.

When you copy text from a website or a document the formatting (font, color, style, etc.) of the text also gets copied. When you paste that text into a document like a report or eMail you are writing you manually have to reformat the pasted text in order to fit the formatting of your document.
This takes a lot of time and is pretty annoying if you do it regularly.

The solution is here: Unformat Clipboard does the job for you! And best of all: with a single click or by hitting ⌥⇪C you can activate and deactivate Unformat Clipboard.
