F3: Trace
Trace
allows you to use the cursor to trace your graph using the left/right arrow keys. It displays
the coordinates of the cursor’s location.
If you want an integer
x
-coordinate, you can press that value and then
and the cursor will
jump to that coordinate. (You cannot specify a
y
-value.)
Example:
Trace to the point that has an
x
-coordinate of 2. Press

to jump to
that point.
