Easier updates to multiple records

[StephenCWills]

System Center lists objects in rows and fields in columns. The Tab and Shift+Tab keys can be used to navigate left and right across the columns, but navigating up and down across rows is not possible. I propose the Up/Down Arrow keys for navigating up and down across rows.

Marked as wontfix for now because mouse can be used for navigating between rows, making this very low priority.
