open vim to edit command line alt+v

Notes for the future:

to have alt-v works I need to set the right alt key to be Esc+ in iTerm2

Q: How do I make the option/alt key act like Meta or send escape codes? A: Go to Preferences > Profiles tab. Select your profile on the left, and then open the Keyboard tab. At the bottom is a set of buttons that lets you select the behavior of the Option key. For most users, Esc+ will be the best choice.
