Remote control question

[ZetaMale]

I bought an Onkyo RC-799M to replace my RC-567M (original remote). The new remote did not come with instructions but it does operate the amplifier. Since it's suppose be able to function as a universal remote I would like it to control my TV and BluRay player but I haven't been able to figure out how to do it. Online manuals and YouTube videos have instructions but apparently there are different versions of this remote. The remote I have doesn't have a "Display" button which appears to be necessary to set it up with the control codes for the various components. Does anyone have alternate instructions? The remote that I have is shown here: Amazon product ASIN B01HPS3P1K
