Equal Rate of Change for Left/Right and Top/Bottom Borders of Source


New Member
Here's what I would like to see available. Here is how the suggestion works: As you're looking at the picture, see the right side arrow which is pointing to the left. I want to grab hold of the vertical border with the mouse and move it to the left, so I can trim the picture down and eliminate the bright red microphone which is on that border.

Here is the crux of the situation: As I move that border to the left, I want the left side border to move an equal distance (same rate of change) to the right. The top and bottom borders don't move during this particular procedure. Just for example, I should hold the [Shift] key down while moving the left/right borders in this manner.

Same rationale applies to the top/bottom borders.

Or, is this feature already available and I just don't know how to use it?
