ListBox - avoid AutoPostBack when Ctrl key pressed

[an]

In a ListBox I allow Multiselection.

I have also the Autopostback property = True

When the user wants to multiselect
and presses Ctrl key and starts clicking on items,
the Autopostback if firerd every time:
it is frustrating.

Is there a way to avoid Autopostback in this case?

An,

I dont think that is possible. You will have post it back during some other
event.

If I let the user enable Javascript,

is there a way to detect somewhere the Ctrl key pressed ?

A sort of:

If key.Ctrl = True then
Listbox1.Autopostback = False
End If

How to correctly write it?
Where to put it?
