Hi, I have a number of items on a canvas, and I am trying to set it up so that the item id is sent to a subroutine when the mouse button is held down, and dragged across the items. The problem is the B1 modifer does not work, as it has to actually be pressed, not just held down. here is the code I tried (Enter is the event for when the cursor enters the widget's space on the canvas): 
$cnv_reference_ref->bind("location$x", '<B1-Enter>' => [\&click_select
+, "$i", "1"]);

I did get this code to work: 
$cnv_reference_ref->bind("location$x", '<Control-Enter>' => [\&click_s
+elect, "$i", "1"]);

So, that I can 'select' things by holding the ctrl key while dragging the mouse over, but I would really like to be able to just hold the mouse button down. thanks
