      While using a ListBox component, if you press any key, "cursor" jumps to next Item starting with that key letter. For instance, if you press "B", it jumps to first Item starting with "B" letter. How to disable that feature?

The easiest way, I think, is to use method onKeyPress.
If you set the referenced "Key" to #0 (char(0)) then
none of the ascii characters typed will work in the listbox.
All other virtual keys (.., VK_UP, VK_DOWN, ...) will work
as they are supposed...

procedure TMainForm.ListBox1KeyPress(Sender: TObject; var Key: Char);
begin
  Key := #0; { Remove all keypresses }
end;

Hope this is what you're looking for!
