I'd like to be able to jump to the first position of the next cell using say PAGE-DOWN key (or any other key is ok). (also jump to the above cell using the PAGE-UP key) Is there a way to do that? I looked at http://reference.wolfram.com/mathematica/tutorial/KeyboardShortcutListing.html and do not see one. i.e. the cursor might be in the middle of a cell, and I'd like it to go to jump to start of the next cell (or the above cell) using one key hit. (I am getting tired of using the arrow key to scroll down and up the notebook) thanks, --Nasser
