In the example below, I have locked my content area to "8MAT" and my school year to "2012-2013." What this means is that I can make all the selections I'd like and when I press clear, my locked selections will remain.
- Notice how locked selections are highlighted in blue and the text turns yellow.
To lock a selection simply do the following:
1) Figure out what your base selections should be. You should only ever really lock selections you do not plan on changing.
2) Press the "Lock" button in the toolbar (learn how to activate the toolbar here)
3) That's it! Now you can make whatever additional selections you would like and not have to worry about clearing them and having to reapply them.
4) To unlock your selections simple press "Unlock"
