Swap the last two expressions in RPN mode with the right arrow key #375

Hi, as an old HP 48GX user I really enjoy the Upsilon RPN mode, however I miss a minor feature that I used a lot : on the HP 48 the right arrow key swaps the last two values of the stack:

Would it be possible to implement this feature in Upsilon too?

You can already swap with the parenthesis (left to swap last three values, and right to swap last two values). Arrows are already used for navigation, but I don't know of it's really useful to navigate in the RPN input (you will probably write at most 3 characters, so you can probably erase to edit instead of using arrows) but then it won't be consistant with the rest of the interface (anyway, RPN is already a bit special for navigation).
