False positive key bindings. Currently jdownloader listens to individual keys within key groupings
select a link/package within link grabber/download tab, hit 'alt + ctrl + delete' or combinations of '(any keys) + delete' it will pick up the delete key as active key binding and will bring up the delete dialogue prompt or if user has already enabled 'do not show this again', will remove package automatically..
tested in stable and nightly.
as we already know key bindings (shortcuts) in current branches is poorly supported, maybe a quick fix to resolve this error as its doesn't obey/usual standards and leave the rest to v1 :>
