Plain text is a text without formatting. There are no bold or italic symbols, you can not use different font styles. Just plain text.

You often copy some text from a web page, paste it to some rtf editor, and get formatting that you do not use. Other font size and color, built-in pictures that you do not need.

In such case you should previously delete formatting from the clipboard, and paste only plain text.

Flashpaste can delete formatting from a clipboard history item before pasting it. Just select the item from the clipboard history, rigcht-click and choose "Paste as plain text" from the context menu. Or simply press Shift+Enter.

Note: This feature works only for items from the clipboard history.
