Need your help on understanding the following:
In the ruler in the top of the powerpoint of word document, i have the following adjustable points:
1. There is an inverted point on the ruler scale
2. There is an upward point on the ruler scale
3. Below the upward point on the rule scale there is a square or a rectangle box
4. I have also observed that an 'L' appears when i try to adjust these scales.
I fully understand that my explanation is rather very crude. Hence I have attached screen dumps from both word and powerpoint with an arrow pointing to the feature I am trying to understand.
