My Calctastic library uses this for inputs in HTML tables. (See example 2.) This is accomplished through the use of my Grid Navigation library, which leans on some very old cross-browser code.

At some point I will update this to use jQuery; until then you are welcome to take and modify the code as you like.

Note that I explicitly do not support (or recommend) right/left navigation using the arrow keys. Users need to use arrow keys to move the caret while editing text. If you hijack the right arrow key to move to the right input, it's going to be very confusing and annoying.
