I am a heavy users of superscripts and subscripts.
After I use
^ to type the content of the superscript, I can exit from it by using the Right arrow key to move to the next variable. However, since in standard keyboards, the arrow key is on the right-hand side of the letter keys, it is a bit inconvenient to move between letter keys and arrow keys frequently. Hence, I wonder if there is any alternative way to exit from the sub/superscripts and move to the next variable without using arrow keys.
