  <span id="title"></span>
  <div id="tbldevs" > </div>
  </div><!-- end of frame -->

You need to simply handle keyboard events, like so:

HTML:

<div id="frame">
    <span id="title">My Title</span>
    <div id="tbldevs">
        <div id="item1"> This is item 1</div>
        <div id="item2"> This is item 2</div>
    </div>
    <input type="button" id="sel-cancel" value="Cancel Select"/>
</div>

JS:

jQuery(function() {
    //make the elements selectable
    $("#tbldevs").selectable();

    //handle the events in every element. Only applies to elements which can be handle focus
    $('*').keypress(function(event) {
        if ( event.which == 100 ) { //this is the keycode. 100 is the 'd' key. The delete key is difficult to bind.
            $('.ui-selected').remove();
            //you can add ajax calls here to remove items from the backend
         }
    });
});

NOTE: The following code only removes the elements from the HTML tree.
