The Cut, Copy, and Paste buttons in the HTML Editor do not function if you are using a browser other than Internet Explorer.
(Note: The Paste from Word and Paste as Plain Text functions work as expected in all supported browsers.)
Pressing the Cut, Copy, or Paste buttons in the HTML editor brings up a pop-up message stating these buttons do not function on your browser.
If using Chrome or Safari, the message is:
"Copy, Cut, and Paste are disabled in your browser. You can use keyboard shortcuts or right-click and choose the appropriate option instead."
If using Firefox, the message is:
"Copy/Cut/Paste is not available on Firefox. Do you want more information about this issue?"
Responding OK (as opposed to Cancel) to obtain additional information directs you to a web site suggesting that you can change your Firefox Preferences to enable these buttons. However, the procedure provided, which had worked in the past, no longer works.
This is a known browser related issue.
To perform the Cut, Copy, or Paste operations in the HTML Editor when not using Internet Explorer, use one of the following workarounds:
Type Ctrl+X, Ctrl+C, or Ctrl+V (on a Windows PC) or command+X, command+C, or command+V (on a Macintosh) to perform the Cut, Copy, or Paste operations, respectively.
Select the text (to cut or copy) or place cursor in the desired position (to paste), right-click, and select Cut, Copy, or Paste from the menu brought up.
