You may notice that when you copy-paste text from Word or perhaps a website, it will include the text formatting. And in some cases you may not want to keep this format. Here are 3 ways you can remove the formatting again.
In the menu of the text editor you have a button that can remove the formatting on the marked text.
Paste as plain text
The button Paste as plain text opens a new window, where you can paste in your text. Then you click OK and the text will be pasted in without any formatting.
Editing the source is the most powerful of the 3, but also the one where you may have to know a bit of HTML. By clicking the Source button, you will open a windows with the source code for the text. Here you can add, delete or change the HTML to suit your needs.
The source window can also be used as a paste as plain text, as it will not automatically include HTML formatting, when you copy-paste into this window.
