I frequently read long .pdf files in tablet mode. I really like the tablet mode for this, especially in a moving vehicle with other people around. To access the "page down" when reading a .pdf file, in laptop mode I just touch the page down or page up button, however in Tablet Mode I have to get the pen out, touch the screen in the right spot, use both hands, sometimes miss the page down icon, etc. Realizing that I hardly ever use the Ctrl-Alt-Del button or the ESC button thats available in tablet mode, it would seem perfect to be able, when desired, to re-assign these keys to page up and page down while reading adobe .pdf files. Has anyone all ready done this, or do you know how difficult this might be to do. Thanks.
