basic functionality in kindle

Hello,

Can someone please help me with the method of going to a certain page in a pdf document in Kindle Paperwhite?

I tap the top left to bring up various links and see the GO TO icon. I tap that twice it brings up several "Loc 000" choices? the first having a + icon in the top right corner. From there it gets crazy for me. I expect the plus to give me a chance to specify a certain page but see no way to input the page I want.

Also. I went through the customization of the appearance and saved the changes but they are not reflected in the view.
