Many of the Calendar Fields used throughout Martial Class, including the Date of Birth and Enrolment Fields, have shortcuts for changing year and month with the mouse.
Other than typing in the date you require, some people prefer to use the mouse, or you may simply use the mouse on the odd occasion, in these instances it's worthwhile to know these shortcuts.
Firstly, when you show the date selection drop down, you see the following:
The Arrows to the left and right go back and forward through the months one at a time, however, you can change the year more quickly by clicking on the year itself in the drop down pane.
This shows the two spin buttons to change the year, using up to advance one year, and down to go back one year.
You can also jump directly to a required month by clicking on the month name in the drop down pane.
Then you can simply click the correct day on the pane to complete your date selection.
