two orientations in same presentation

[mwuest3]

I want to have portrait and landscape slide orientations in the same presentation. According to MS Word instructions, you have to link two presentations to display both orientations in what appears to be one presentation. But I was not able to follow their instructions. To start out with, they said to select the text or object that you want to click to link to the second presentation. Then on the Insert tab, in the Links group, click Action. But nothing happened. So clearly I did not understand what they meant in the first step. Thanks for any help.
