I installed a PDF on my Kobo Aura mainly to see how it looks. It's actually a Christmas songs book. And, yes, it looks okay. And I can change pages by swiping the screen.
I've figured out that double tapping seems to increase the size, and more tapping eventually brings it back to normal.
Tapping in the <control> section of the screen brings up the expected menu, just like an epub.
Biggest concern is that when I access a page from the table of contents it displays in a 1/4 size format. Double tapping seems to bring it back to normal size.
Can't find an instructions sheet anywhere either
I should add this is with a the default PDF software on the kobo.
