Im using a treeview, when i hit left arrow in keyboard the selected item in treeview expands and when i hit down arrow key the next item in the treeview is selected..So here I have two Buttons btnStepIn, btnStepOut which should exactly act like left and down arrow key..On btnStepIn button click right arrow key functionality should be performed and on btnStepOut button click down arrow key functionality should be performed..

See this may be its helpfull, you can capture keypress like that in jquery.

$(document).keydown(function(e) { 

       switch(e.which) {
      case 37: // left
      break;

       case 38: // up 
       break; 

       case 39: // right
      break; 

       case 40: // down 
       break; 

       default: return; // exit this handler for other keys
}     
e.preventDefault(); // prevent the default action (scroll / move caret) });
