Mark the area which is to be commented using the *blockwise* visual mode (CTRL-V, in Windows this is CTRL-Q).
Press I (capital i) and write the text you want to prepend to each line of the selected block, e.g. %.
Then press ESC and the text will be inserted to the left of each line of the selected block.

So… What’s an easy way to UNcomment it? Or should I go the script route? (Found several.)

James: it’s even easier than commenting stuff out: You use CTRL-v to block mark just the comment characters (which is easy, they are in equal amounts at line beginnings), than just press d to delete the block of text. And it is as if you never commented anything out 😉
