The Copy and Paste functions are some of the most important fundamentals to master for manipulating objects on yor computar. See the Right-Click section on your mouse.

You can use the following functions:

ctrl + c -----copy

ctrl + v -----paste

ctrl + a-----choose all

ctrl + x -----cut

Cut and Copy are two different functions of Word. Cut will take the Highlighted text from your word document and delete it. When you paste it will move the deleted text to where ever you paste. Copy just dupilcates the highlighted text where ever you paste.
