Ctrl + right arrow moves to the end of a word. Game. Changer.

And paired with this:

* Ctrl+backspace/delete to delete an entire word at a time.

* Ctrl+shift+left/right arrow selects entire words at a time.

macOS has emacs style key bindings like this OS-wide.

Ctrl+e: end of line

Ctrl+a: beginning of line

Ctrl+p: go up a line

Ctrl+n: go down a line

Ctrl+f: go forward a character

Ctrl+b: go back a character

etc...
