The ability to Cut, Copy, & Paste text isn't necessary to edit your webpages or add HTML provided by online services but it sure makes the job a whole lot easier. Prior to the upgrade that added the ability to our boxes adding the HTML for say a guestbook was a gruelling experience. Unless you had excellent typing skills and the eyes of a hawk it could be a frustrating adventure. It's a very easy technique to learn involving just a few keystokes so let's get started!
Listed below are the keys you will use.
All you are doing is selecting a specific amount of text, storing it in temporary memory, and then placing it wherever you wish. Selecting text is done by first highlighting it. Once highlighted that text can be copied. If you are in a text area (webpage editor or e-mail) you can also cut text. Cutting text removes the highlighted text. This is very handy in moving paragraphs or sections of your webpage around. Text stored in temporary memory remains there until you either copy or cut new text or power off.
Holding down the CMD key and pressing the letter A will highlight all the text on a page or in a text area. (a text area would be wherever you have the ability to edit or add text - examples are your webpage editor or your e-mail write screen).
Holding down the CMD key and pressing the letter C will copy any highlighted text to a clipboard of sorts in your temporary memory.
Holding down the CMD key and pressing the letter X will extract any highlighted text (from a text area only!) from view but store it in memory. This is very useful if you want to change the order of paragraphs or items when editing a webpage or letter!
Holding down the CMD key and pressing the letter V will copy the text stored in memory to the location you designate as indicated by the position of your flashing cursor.
The Shift key and arrow keys allow you to highlight text character by character or a line at a time. In a text area place your cursor at the beginning or end (doesn't matter : ) of the section you wish to highlight. Hold down the Shift key and use the arrows to highlight as little or a much text as you wish. If the text you wish to highlight is part of a webpage you'll need to use your Find key.   Press Find and in the pop-up box type the first few words of the text you wish to copy. Press return and the those words will be highlighted. Hold down the Shift key and use the arrow keys to highlight any additional text. When complete press CMD + C to copy that text to memory.
Your cursor is positioned in the first text box....Press CMD+A to highlight the text.   Release the A and press C to copy it. Tab down to the second box and Paste the text by pressing CMD+V..DaDaaaaah!
