-Block-wise visual mode works with rows and columns. It gives you more freedom of movement than the other two modes.

 There are three ways to exit the visual mode: `<Esc>`, `Ctrl-C`, and the same key as your current visual mode. What the latter means is if you are currently in the line-wise visual mode (`V`), you can exit it by pressing `V` again. If you are in the character-wise visual mode, you can exit it by pressing `v`.
