There is a shortcut
N that will jump to another post in the same feed ("subscription") but will not jump to another feed when the current post is the last one.
Then there is a
spacebar shortcut that will scroll down one page and switch to a next feed if necessary but if a post is very very long, I have to hit the spacebar many times in order to reach the next post.
Is there something like
N that will also take me to the next feed if necessary?
