Cursors at Same Position. If both cursors are at the same position, and
H Bars or V Bars are set to Ratio or Phase, both cursors are set to 0%
(or 0°). 100%/360° is set to one pixel width away from the cursor
position.
V Bars and FFT. When the selected waveform is an FFT waveform,
selecting V Bars and Phase sets the measurement to percent.
Tracking Mode. In cursor tracking mode, both cursors move together
when cursor 1 is selected. Enabling tracking mode automatically
selects cursor 1 as the active cursor. If cursor 2 is selected while in
tracking mode, only cursor 2 will move.
