HP Prime Graphing NW280AAABA manual Selecting an, Object, Hiding names, Moving objects

	four vertices are named D, E, G, and H. Moreover, each of
	the six segments is also given a name: I, J, K, L, M, and N.
	These names are not displayed in Plot view, but you can see
	them if you go to Symbolic view (see “Symbolic view in detail”
	on page 148).
	Naming objects and parts of objects enables you to refer to
	them in calculations. This is explained in “Numeric view in
	detail” on page 150.
	You can rename an object. See “Symbolic Setup view” on
	page 150.
Selecting an	To select an object, just tap on it. The color of a selected item
object	changes to cyan.
	To select a point in Plot view, just press E. A list of all
	the points appears. Select the one you want.
Hiding names	You can choose to hide the name of an object in Plot view:
	1. Select the object whose label (that is, caption) you want
		to hide.
	2.	Press Z.
	3.	Select Toggle Caption.
	4.	Press J.
	Redisplay a hidden name by repeating this procedure.
Moving objects	Points To move a point press E. A list of all the points
	appears. Select the one you want to move, then tap on the
	new location for it, and press E.

You can also select a point by tapping on it.

In addition to tapping a new location for a selected point, you can press the arrow keys to move the point to a new location, or use a finger to drag the point to a new location.

A point can also be selected directly by tapping on it. (If the bottom-right of the screen shows the name of the point, you have accurately tapped the point; otherwise the pointer coordinates are shown, indicating that the point is not selected.)

Composite objects To move a multi-point object, see “Translation” on page 161.
