An easier way to copy to the clipboard

Hi all. As any of you know who've dealt with me on skype knows, I don't always know or do, the easy commands. Lke command C to copy, I tend to voice over shift M, arrow down, click copy. Is there a keyboard shortcut to append to whatever's on the clipboard? Say you have a book, you want to select both parts. Part one, no problem. what about part two? Thanks for any help.
