The coordinates of the blinking cursor's location appear at the bottom of the screen.

Press or to move the cursor along the graph from one plotted point to the next.


Note: Press or to move the tracing cursor to the next function. The cursor moves to the new function at the same x value.

If tracing a graph takes the cursor off the display screen to the left or right, the viewing window pans to show the new cursor location provided it does not scoll off the window vertically. The window settings are updated accordingly.



If tracing a graph takes the cursor off the display screen vertically, to the top or bottom, the cursor disappears from the screen. However, the x and y coordinates of the cursor are displayed at the bottom of the screen.



Press zooms-in on the last displayed point changing the viewing window so that the cursor location becomes the center of the window.
