jQuery Grid Plugin - jqGrid

I would like to see some simple keyboard navigation options made available when browsing through records in the grid.  Here's what I propose:

Up-Down arrows: change the selected row...if no row is selected, first down arrow press selects the first row.

Left-right arrows: changes the page if paging is enabled.

Shift-Left/shift-right arrows: first page/last page.

if more than one grid is on a page, then either have a way to enable/disable this feature (per grid), detect which grid has focus, or use modifiers (such as ctrl or alt keys)

Also, I have used the jquery plugin HotKeys to bring up the search dialog, but i have to refine the search options in the function. I'd like to see methods exposed that would have the same effect as clicking the search, edit, add, etc. buttons.  that way, i could assign HotKeys to run those functions without re-initializing them each time they are run.

Thanks,
