More effective way of moving cursors

Hi.

In math mode, one type ‘a _ i’, the cursor stays at the subscript.

  • What is the effective way to move out of the subscript? Hitting the arrow key seems not effective.

  • What I did is to rebind the var to “;” the semicolon and re-bind TAB for cursor movement.

  • Any other ideas?

If you switch the look and feel to Emacs, you may use Ctrl-F to move the cursor forward.
