One could also use M-f and M-b to move one word at a time instead of one character at a time.
M is short for the Meta key, on your keyboard it will probably be Alt.
Page up is M-v. Page Down is C-v.
End of Line is C-e. Beginning of the Line is C-a.
So much for moving around.
The most common method of copy&paste is by cutting out using C-k. C-k cuts until the end of line, typing C-k many times will cut many lines. If you cut a few lines then move around and cut more lines. The first lines would be lost this way (not including possible undo).
In order to paste we will yank the text out of the buffer using C-y you can yank(paste) out however many times you want wherever you want.
