Hi,

At this time there is no built-in support for selection navigation using the keyboard in WpfPlanner. You can handle the appropriate Key* event of the Calendar control and perform the necessary selection adjustments through the Calendar.Selection object manually. For example, the following PreviewKeyDown event handler can be used to modify the selection by using the Left and Right arrow keys:

if (e.Key == Key.Left || e.Key == Key.Right)
{
	if (_calendar.Selection.IsEmpty)
		return;

	e.Handled = true;
	if (e.Key == Key.Left)
	{
		DateTime first = _calendar.Selection.Ranges[0];
		first = first.AddDays(-1);
		_calendar.Selection.Set(first);
	}
	else
	{
		DateTime last = _calendar.Selection.Ranges[_calendar.Selection.Ranges.Count - 2];
		last = last.AddDays(1);
		_calendar.Selection.Set(last);
	}
} 

Regards,
