I am using Ubuntu 14.04. with Unity DE.
How can I make keyboard shortcuts work on key release, not on key press?
For example, if I want to use the windows key for multiple shortcuts, it works only for the one that's triggered by the win key alone, because the shortcut works before the next key press is registered.
I am using Ubuntu. Is it possible to check md5sum of a video using its URL?

Also, on what factors do the limit depend?
The question is simple and straight forward:
