Navigation with command key + arrow

[Jmuccigr]

It'd be great to navigate the table by cell instead of by row, but I suspect that's a big change. A smaller one would be to allow command-arrow to work as it normally does, sending the selection all the way to the top or the bottom of the table.

(If navigation were by cell instead of by row, it might make more sense for command-arrow to work more as it does in Excel and other spreadsheets, sending you to the last cell in the sequence which has contents or not (depending on the current cell).)

Please find a list of all Excel navigation/selection shortcuts we might consider to add and then make a complete proposal for which conventions we should adopt. This will get closer to the solution here.
