Vim "yank" does not seem to work

vim, yank

Solution

`y`ank by itself merely copies the line into a clipboard - you will need to `p`aste it onto the next line or onto the `P`receding one to use the copied line. To cut the line as well, use `d`elete.

Problem

I'm fairly new to Vim. Tonight, I learned about the "yank" command, but when I try to use it in MacVim, it doesn't do anything. Neither `Y` nor `y{motion}` do anything. I tried with a default `.vimrc` to rule out any weird config issues. Google-fu is failing me. This feels like a noobie issue. Am I missing something obvious?
