Immediate response to buttons pressed

[Sergio-Navarro-M]

Hello all,
How can I configure digital buttons to trigger the interrupt routine as fast as possible? With the single press it is triggered after the button is released.
A workaround for me would be to configure a long press event with a very short timeout (10 ms?). Is it the best way to implement it or are there more "elegant" ways to achieve this behavior?

Thank you in advance for your help and thanks for this handy library.

Best regards,
Sergio
