Set Option-arrow navigation in iTerm2

gistfile1.txt

~/.inputrc content:

"\e[1;5C": forward-word
"\e[1;5D": backward-word

Config profile keys in preferences of iTerm2

Then I had to set up in iTerm2 preferences–under Profiles->Keys–the options for both key combinations:

Add a hotkey with the plus symbol at the bottom of the hotkey list
Set the keyboard shortcut by pressing Option-left or Option-right
Set the action to “Send Escape Sequence”
Set the Esc+ field to:

[1;5C (Option-Right)
[1;5D (Option-Left)
