The Lock check box next to the Offset text box, when using "pick lines" is available when the offset value is zero. It means that you can pick a line as a reference and have the element aligned and locked at the same time, without you having to do align & lock in two separate steps.

In the illustration provided, there is a wall. I want to create a grid line that is aligned and locked to the center line of the wall. Then I use Home > Grid > pick lines > offset = 0.0 > activate "Lock" > pick the center line of the wall. The result is that the new grid line is both aligned and locked in one single step to the centerline of the wall.
