Cursors are used primarily for temporary indicators of sample position and are expected to be moved frequently, as in the case when you are measuring the distance (in samples) between two waveform edges.
You can place the main cursor with a single click in the Waveform window.
To place a secondary cursor, Ctrl+Click and hold the waveform, and drag either left or right. You can see a flag that labels the location at the top of the cursor.
Alternatively, you can hold the Shift key and click a point in the waveform. The main cursor remains in the original position, and the other cursor is at the point in the waveform that you clicked.
To move a cursor, hover over the cursor until you see the grab symbol and click and drag the cursor to the new location.
As you drag the cursor in the Waveform window, you see a hollow or filled-in circle if the Snap to Transition button is selected, which is the default behavior.
- A hollow circle
indicates that you are between transitions in the waveform of the selected signal. - A filled-in circle
indicates that you are hovering over the waveform transition of
the selected signal. A secondary cursor can be hidden by clicking anywhere in the
Waveform window where there is no cursor, marker, or floating ruler.
