Fast way

1. Run this command:
    echo '{"Touch Bar Items":[],"Key Mappings":{"0xf700-0x260000":{"Action":10,"Text":"[1;6A"},"0x37-0x40000":{"Action":11,"Text":"0x1f"},"0x32-0x40000":{"Action":11,"Text":"0x00"},"0xf709-0x20000":{"Action":10,"Text":"[17;2~"},"0xf70c-0x20000":{"Action":10,"Text":"[20;2~"},"0xf729-0x20000":{"Action":10,"Text":"[1;2H"},"0xf72b-0x40000":{"Action":10,"Text":"[1;5F"},"0xf705-0x20000":{"Action":10,"Text":"[1;2Q"},"0xf703-0x260000":{"Action":10,"Text":"[1;6C"},"0xf700-0x220000":{"Action":10,"Text":"[1;2A"},"0xf701-0x280000":{"Action":11,"Text":"0x1b 0x1b 0x5b 0x42"},"0x6c-0x100000":{"Text":"[C","Action":10},"0x38-0x40000":{"Action":11,"Text":"0x7f"},"0x33-0x40000":{"Action":11,"Text":"0x1b"},"0xf703-0x220000":{"Action":10,"Text":"[1;2C"},"0xf701-0x240000":{"Action":10,"Text":"[1;5B"},"0x4c-0x160000":{"Text":"","Action":34},"0xf70d-0x20000":{"Action":10,"Text":"[21;2~"},"0xf702-0x260000":{"Action":10,"Text":"[1;6D"},"0xf729-0x40000":{"Action":10,"Text":"[1;5H"},"0x69-0x140000":{"Text":"[A","Action":10},"0xf706-0x20000":{"Action":10,"Text":"[1;2R"},"0x34-0x40000":{"Action":11,"Text":"0x1c"},"0xf700-0x280000":{"Action":11,"Text":"0x1b 0x1b 0x5b 0x41"},"0x6a-0x100000":{"Text":"[D","Action":10},"0x4a-0x160000":{"Text":"","Action":33},"0x6a-0x80000":{"Text":"b","Action":10},"0x2d-0x40000":{"Action":11,"Text":"0x1f"},"0xf70e-0x20000":{"Action":10,"Text":"[23;2~"},"0xf702-0x220000":{"Action":10,"Text":"[1;2D"},"0xf703-0x280000":{"Action":11,"Text":"0x1b 0x1b 0x5b 0x43"},"0xf700-0x240000":{"Action":10,"Text":"[1;5A"},"0xf707-0x20000":{"Action":10,"Text":"[1;2S"},"0xf70a-0x20000":{"Action":10,"Text":"[18;2~"},"0x35-0x40000":{"Action":11,"Text":"0x1d"},"0xf70f-0x20000":{"Action":10,"Text":"[24;2~"},"0x6c-0x140000":{"Text":"","Action":0},"0xf703-0x240000":{"Action":10,"Text":"[1;5C"},"0x6b-0x140000":{"Text":"[B","Action":10},"0xf701-0x260000":{"Action":10,"Text":"[1;6B"},"0xf702-0x280000":{"Action":11,"Text":"0x1b 0x1b 0x5b 0x44"},"0xf72b-0x20000":{"Action":10,"Text":"[1;2F"},"0x36-0x40000":{"Action":11,"Text":"0x1e"},"0x6a-0x140000":{"Text":"","Action":2},"0xf708-0x20000":{"Action":10,"Text":"[15;2~"},"0x6c-0x80000":{"Text":"f","Action":10},"0xf701-0x220000":{"Action":10,"Text":"[1;2B"},"0xf70b-0x20000":{"Action":10,"Text":"[19;2~"},"0xf702-0x240000":{"Action":10,"Text":"[1;5D"},"0xf704-0x20000":{"Action":10,"Text":"[1;2P"}}}' > /tmp/iterm_key_presets.itermkeymap

2. To set these bindings in iTerm2, go to Preferences->Profiles->Keys and then Presets->Import. Import the file '/tmp/iterm_key_presets.itermkeymap'.

Explanation:
esc-f and esc-b  :  Move by word. Will work in Python and other shells as well.
esc-[A  :  Equivalent to up    arrow key.
esc-[B  :  Equivalent to down  arrow key.
esc-[C  :  Equivalent to right arrow key.
esc-[D  :  Equivalent to left  arrow key.

You can run `od -c` at the terminal to see the escape sequence / keycode of anything you type.

In the below table, "^[" means "esc-".

To set these bindings in iTerm2, go to Preferences->Profiles->Keys and add these to the table. You can choose "Send Escape Sequence" as the action, and then type (for example) "[A" in the "ESC +" field.
