Month and year navigation items aren't keyboard-selectable

dbusmenu lacks support for table menu items

I've created the following bug to group these calendar widget related issues;

"IDO calendar should replace GtkCalendar wrapper with a grid layout menu"
https://bugs.launchpad.net/ubuntu/+source/ido/+bug/742370

I don't understand this bug report. Holding down Ctrl while selecting left/right arrow key works to change the month on my computer. Holding down Ctrl while selecting up/down arrow key works to change the year. What exactly is the bug?

I don't want the month changing simply from pressing the arrow keys. That should be reserved for just navigating to dates within the month.

The menu contains items for navigating to the previous and next month and year. It is not possible to navigate to those items with the keyboard. That is the bug.

That there are keyboard combos for navigating between months or years directly is a nice subtlety, but it is not a solution to this problem. Until your comment I didn't know those combos existed (thanks, by the way!), and I expect at least 95% of other people who opened the menu wouldn't guess that they existed either.

The design does not involve the month changing simply by pressing arrow keys. See <https://wiki.ubuntu.com/TimeAndDate#Monthly_calendar> for more details of how the calendar is supposed to work.
