The Anno Active Cursors are very versatile. You have the option of setting the value of the window in which the cursors operate within. The precision of the value displayed can also be set.
In this example,

The blue cursors show the three active cursors positioned within the cursor window. The green cursors show the two outer cursors positioned to the min and max values of the cursor window.

The cursor window is defined by the outer lines that have no text call out boxes. Note that you also have the option to hide the cursor window lines.
