It's easy to learn. Try this: Put your mouse over the first letter that you want to copy. Now left click and hold that left "clicker" down until you get to the end of what you want to copy. It will all be highlighted. Then let up on the clicker.
With your mouse over the highlighted portion, right click on the mouse. A box will drop down. Click on "copy".
Next, go to the page where you want to paste it (have an e-mail page open with my address in the address line). Put your mouse on the area where you would normally type your letter. First left click on your mouse (to activate the cursor in that box) and then right click. In the drop-down box click on paste. And now you should see everything that you wanted to copy and paste.
Of course, I could look back at the information I sent you instead of having you try this (and I will if you have trouble), but it will be such a useful tool for you, especially with all those names and dates to enter in your genealogy, that you really must try it. It might sound complicated, but it's not. You can do it!
