- Move the mouse vertically upwards to lower the window center (increase the perceived brightness).
Tip: Use Preferences to reverse the direction of level adjustments.
Drawing a Segment
You can draw a segment in two ways:
- Click + Drag: Click, drag to draw, then release.
- Click > Release > Drag: Click to start, release, drag to draw, and release again.
