You can copy and paste in the wysiwyg editor in two ways.
1) Using CTRL + C in the original document & Ctrl + V in the wysiwyg editor
However, it should be borne in mind that this sometimes copies additional formatting that is not allowed in kañooh.
An example of such additional formatting is font size, color, and the like when you would copy from Word.
This will be filtered out after saving the page. (See full list of allowed html tags)
2) Use the "paste as plain text" button or right-click and then paste.
This will put everything you copy into it straight to plain text. So no extra formatting is included.
(Such as custom color, font size, etc ...)
