Hello - I have a user who is visually indicating a separation in data on his
chart by drawing a line from the category axis to the top of the plot area.
He is using one of the tick markers on the category axis as his start point.
The question is this:

If he is off the tick marker a little, is there a way to nudge the line into
position, or is manually dragging the only way to move the line?

For example, drawn objects can be nudged into position using the arrow keys
on the keyboard, or CTRL with the arrow to nudge in even smaller increments.
When the drawn object is on a chart, however, using the arrow keys just moves
you between other areas of the chart. It won't nudge the drawn object.

Thanks for any suggestions!
