jQuery Grid Plugin - jqGrid

I have a grid which is working well. I have form editing set up. I can invoke the edit form with the edit button in the nav bar, and by double-clicking on a row in the grid. I also want to be able to fire the edit form with a keystroke, specifically they "e" key.

I've tried adding a keystorke handler to the document, and that works when the grid doesn't have focus. Is there something in the grid which does not allow keypress events to bubble up?

I've been unable to find any documentation on how to get the grid to respond to keypresses.

Suggestions? Thanks!
