Copy=Highlight by left clicking on your mouse & dragging across everything you want to copy then let go of the mouse.(Everything will be highlighted in blue) Then-on top of the highlighted item-Right click with the mouse. You will have options, click the "copy" word. Now..
Paste =do a right click on wherever you want to "paste" what you just copied. There will be options there.. left click on the word paste.. and viola.. there is your copy.
therefore.. whatever was the last thing you copied will stay "inside the mouse"per say... until you highlight & copy something different.-so I just clicked paste twice and gave 'double Merry Christmas" LOL
Hope this helps!
