tilcommand-z in vim

Vim, run from the terminal, does not make use of the Command key. So most of my muscle memory has been lost while learning it. However I found a shortcut: iTerm’s key mapping.

In iTerm, open Preferences (or press Command-, and in the Keys tab add a new Key Binding.

• Keyboard Shortcut: ⌘z

• Action: Send text with “vim” Special Chars

• Value: \<M-u> (The backslash is important)

Now within the terminal, hitting Command-Z (Undo) will map to Meta-U, which will perform Undo in Vim.
