Can less follow (by pressing F) a piped input (similarly to a file)? For a file that is being written to, the command

less <file> 

will follow the file when pressing F.

But if I have a command that pipes output directly into less, like this

command | less 

pressing F will do nothing.

So it looks like pipes cannot be followed like files can? Or maybe it has to do with command also writing to STDERR? The effect I'm trying to achieve is always see the latest output of the command: just like keeping PageDown pressed!

A related remark holds for G (go to end): when piping directly to less, it won't work.
