FIND	Lets you display the trend from a certain time. A list of times will appear on the display, as
	shown. FIRST is the oldest time available in the trend. LAST is the most recent time
	available.

	LAST:	JAN	5	1994	13:00
	FIND:	JAN	1	1994	12:00
	Select month, day, year, hour and minute. To cancel the search, press Display, Menu,
	Display1, Display2 or Display3 buttons.
	When the data has been found, the selected time/date will appear in the center of the trend
	area. The Point/Detail menu will also appear.
ZOOM	Lets you magnify (zoom) the displayed scale.
	Press the Increment and Decrement buttons to select the amount of magnification, shown in
	the lower right corner of the display. Note that the size of the Zoom cursor changes
	accordingly. See Figure 6-3.
	OFF – uses point’s trend display limits (turns Zoom off)
	2X – uses half of point’s trend display limits
	4X – uses one fourth of point’s trend display limits
	FULL – uses point’s programmed limits (not its trend display limits)
	Press the Tab key to select the point/trace to be zoomed (magnified).
	Press Enter to display the magnified trend. The Point/Detail menu is displayed to allow
	further analysis.
	Press the Display button to restore the primary display with the ZOOM limits. A “Z” appears in
	the lower right of the display.
TIMEBASE	Lets you change the timebase of the trend. Choices are:
	NORMAL – use the trend’s normal timebase.
	ALTERN (Alternate) – use the trend’s alternate timebase.
	Move the cursor box to			the desired timebase and press Enter. The trend will be redisplayed
	in the new timebase. An arrow points to the current timebase. Timebases are specified in
	the program mode. Available for live trends only.
	If a storage trend CHANGE WITH KEY is set to YES, then changing the timebase will also
	change the storage rate of the storage trend. That is, if the live Trend1 is displayed in
	NORMAL timebase, then the storage Trend1 will be stored at the LOW rate. If the live
	Trend1 is displayed in the ALTERN timebase, then the storage Trend1 will be stored at the
	HIGH rate. Trend2, 3 and 4 behave the same way.
NEW FILE	Select to see the Replay From Disk menu, from which you may select another stored file for
	replay. Available for replay trends only.
