24 Using the Scratchpad
4. Press · at the point to start the search. The tool shades the range.
If the search region you specified includes the point of interest, a
label for the point displays. If you change a graph that has points of
interest identified, be sure to check for changes in points of interest.
For example, if you edit the function on the entry line or manipulate
a plot, the point where the graph intersects zero can change.
The labeled points of interest remain visible on the graph. You can
exit the tool by pressing
d or choosing another tool.
Working with variables in the Scratchpad
Scratchpad variables are shared between Scratchpad Calculate and
Scratchpad Graph, but not with any TI-Nspire™ documents. If you use the
same name for a Scratchpad variable and a variable in a document, no
conflict occurs unless you attempt to copy expressions between
documents and the Scratchpad.

or both as a TI-Nspire™ document.
