iTerm2 on Mac OSX: add alt-left, alt-right and alt-backspace behaviour

iterm-cursor-settings.md

If you want iTerm2 to behave like the other Mac OSX applications, so that alt + left moves the previous word, alt + right moves to the next word and alt + backspace deletes the whole word, add these keyboard shortcuts from iTerm > Preferences > Profiles > Keys:

• Alt + left: Send Escape Sequence, Esc + b
• Alt + right: Send Escape Sequence, Esc + f
• Alt + backspace: Send Hex Code, 0x17
