You can only jump by word, forwards and back, by holding the option key while using the arrow left and right.

Backspacing however can be done by word by using c-w to delete back by word. Unfortunately this hotkey only works in terminal I think, so you'd have to do option+backspace in chrome, etc.

I don’t think option arrows work in terminal. I’m only able to go to beginning or end of line and with long lines that’s not ideal.

Iterm2, built in Terminal, bash shell.

Ah i see, interestingly I don't ever write "text" or sentences in iterm so I dont usually have to delete by word or even skip by word. But this may help: https://medium.com/@jonnyhaynes/jump-forwards-backwards-and-...
