Spectrum Cursor Track

Macro: SpectTrack

When the Track option is active, the solid cursor is automatically positioned over the largest spectral peak at all times. (You will not be able to move the solid cursor manually in this case.) The dotted cursor is not affected.

This is especially useful with cursor Peak mode for precision tracking.

You can toggle Track at any time via the ALT+4 accelerator key. As a reminder, note that the $ which shares the top-row 4 key can be thought of as a vertical cursor line with a "wiggle" S symbol over it.


Macro Notes:

SpectTrack=1 sets Spectrum Cursor Track mode, SpectTrack=0 turns it off, and SpectTrack=x toggles between on and off.
