Ex-link Smarthub command

I have a new Samsung HU8550 4K TV which I am controlling using the Roomie Blaster + Ex-Link. As with most TVs this one has a Netflix app, HBO, etc. However, there seems to be no Ex-Link command to bring up the Smarthub menu which then lets you access Netflix, etc. Anybody have any ideas? The funny thing is that the Ex-link cursor commands do allow you to move around the Smarthub stuff once the menu pops up. You can also, through a complicated menu process, get Smarthub to pop up via Settings but this is pretty tedious.

It’s there. It’s just called INPUT SMARTHUB. Sort of confusing name, but SmartHub is more or less like an input. Direct commands also exist for Amazon, etc. in that list.

Thank you.
