It is definitely required for Windows L&F as excel also has same functionality for CTRL+SHIFT+UP/DOWN but I amnot sure if spec mandates it for all L&F...Did you see anywhere in spec that ctrl shift up/down should select all populated cells in the column.
Please check in linux and macos if native spreadsheet has same functionality, if not restrict it to Windows only...

Also, add bugid to the existing jtreg test...it may be recommended to modify the deprecated applet based test, since you are relying on that test to test this fix, to normal manual PassFailJFrame based test
