Shift lets you review past text. It can be a bit laggy if it's loading lots of text, but should work. What do you mean by "change what text you skip?" Alt just fast forwards through text, it's not really a programmed skip function or anything, so I don't think I could change that. And I just checked, but it seems the skip function is one of the things that can't be rebound, unfortunately. Sorry about that. If you don't have the game fullscreened and you click out of the window before pressing Alt+Tab, I believe that would avoid skipping text. Sorry I couldn't help further.
