Keyboard shortcuts for Adobe Behance Videos

Can't tell if this is the right community.  If not, apologies. 

I like to watch tutorials on Behance.  However, I have no idea what keys (if any) will advance or rewind the video (like 'j' and 'l' and arrow keys on YouTube).  I know that I can scroll the progress bar with a mouse, but often I just want to hear some tip again and the mouse scroll is not the best.  For this reason, I give up the chat function on videos from Terry White and watch on YouTube.  Alas, not all Behance videos seem to show up on YouTube.  Any ideas?  I've tried 'j' and 'k' and the arrow keys, cntl-arrow and alt-arrow to no avail.
