How to keep cursor stil when jump among months

[huangyg11]

In the calendar, when I press <left>, the months are shift down and the cursor is move to the "<Prev" in the nav bar. What I want is the position of cursor doesn't change. It is not the option of "calendar_focus_today". With this option set to 1, the cursor still change because it keep tracing today until the date is out of window. Take an example. Now the cursor is in the date 2.1. then I press <left>, then the cursor stays still and it points to 1.1 .(maybe it does moves a little because the difference of months).
