With regard to learning the commands, at one point the learned >| button worked as 'Home'. They broke that in the 14.6 release I think.
I picked up the latest remote for ATV and also found that a quick touch of the enter pad will show you current time vs run time for a program. I have not found a solution via IR commands above for that as of yet.
But if you have an application such as HBO Max that offers >>| for 'Skip', you can do a quick tap of the Select command above and it should skip.
