SUMMARY
System Monitor's Processes view doesn't properly handle up/down arrow keys: They should change the selected process, but they simultaneously scroll the view (by a weirdly large amount: several rows at once). This makes the arrow keys practically impossible to use for navigation, since almost any use will scroll the new selection out of view.

STEPS TO REPRODUCE
1. Open the Processes view in System Monitor
2. Select any process
3. Press the "down" arrow key 

OBSERVED RESULT
The selected process changes, but also the entire process view is scrolled down.

EXPECTED RESULT
The selected process changes, and the process view should only be scrolled if the the new selection is out of view.
