iTerm is a cool terminal replacement for OS X (tabs, bookmarks, and profiles off the top of my head); I’m still using Tiger, I think Leopard’s terminal app has been improved, but I’m not sure how it matches up to iTerm.

I like to use Command (Apple key) + left and Command + right to skip to the beginning and end of lines respectively, unfortunately iTerm doesn’t understand these shortcuts out of the box (although you can use Function + left and right). To enable this:

1. Open iTerm
2. Bookmarks menu > Manage profiles
3. Keyboard profiles > Global
4. Click +
5. Key: cursor left, Modifier: Command, Action: send escape sequence “OH”
6. Click “High interception priority” and then OK
7. Click +
8. Key: cursor right, Modifier: Command, Action: send escape sequence “OF”
9. Click “High interception priority” and then OK

You can also set up Alt + left and Alt + right to navigate between whole words, the commands are:

• Key: cursor left, Modifier: Option, Action: send escape sequence “f”
• Key: cursor right, Modifier: Option, Action: send escape sequence “b”
