A faster alternative for arrow keys? When editing texts, left and right arrow keys are frequently used. But it takes quite some time to move your right hand from the letters section to the arrow keys.

I used to use a Sony laptop, on which I could press "fn" with my left hand and then press "u" and "o" with my right hand to achieve the functions of "left arrow key" and "right arrow key", so my right hand seldom moved away from "jkl;". Neat.

Is there a similar resort on Mac?

Thanks!!
You can use this :


ctrl+A: beginning of line.
ctrl+E: end of line.
ctrl+U: delete from cursor to beginning of line.
ctrl+K: delete from cursor to end of line.
ctrl+W: erase word to the left.
ctrl+T: transpose characters around cursor.
