iTerm Keyboard Shortcuts for Navigating Long Lines of Text

I often have to edit long lines of text (_e.g. commit messages_) in iTerm
and find my self wanting to jump to the start of the block of text.

* Ctrl+A, jumps to the start of the line, while
* Ctrl+E, jumps to the end of the line.

These are the built-in keyboard shortcuts, but it's easy to define your own custom ones:
