The ways described here are quite convenient for sure, but since
comments are pretty important and frequently-used instruments in
programming, I prefer extending the conveniency furthermore by using
"The NERD Commenter" vim plugin found here:

To comment out the 5 following lines just type 5,c<space> or 5,cs to use
multirow comments.
