Setting parameters for a screen

To control how the screen appears and behaves during playback, set parameters on the Parameters tab of the

Property inspector. Different parameters are available for slide and form screens.

The following parameters are available only for slide screens:

• The autoKeyNav parameter determines whether the slide uses default keyboard handling to control navigation to

the next or previous slide. When

autoKeyNav is set to true, pressing the Right Arrow key or the Spacebar

advances to the next slide, and pressing the Left Arrow key moves to the previous slide. When

autoKeyNav is set

false, no default keyboard handling takes place. When autoKeyNav is set to inherit (the default setting),

the slide inherits its

autoKeyNav setting from its parent. If the slide’s parent is also set to inherit, the parent’s

ancestors are examined until one is found with its

autoKeyNav parameter set to true or false.Ifaslideisaroot

slide, setting

autoKeyNav to inherit yields the same result as setting it to true.

Note: This property can be set independently for each slide, and it affects keyboard handling when that slide has focus.

• The overlayChildren parameter specifies whether child screens overlay one another on the parent screen during

playback. When

overlayChildren is set to true, child screens overlay one another. For example, suppose you

have two children, Child 1 and Child 2, which are bullet points on the parent screen. If the user clicks a Next

button and displays Child 1, then clicks Next again and displays Child 2, Child 1 remains visible when Child 2

appears. When

overlayChildren is set to false (the default setting), Child 1 is removed from the display when

Child 2 appears. This parameter affects only the immediate children of a slide, not nested descendants.

• The playHidden parameter specifies whether a slide continues to play if it is hidden after being shown. When

playHidden is set to true (the default setting), the slide continues to play when the slide is hidden after being

shown. When

playHidden is set to false, the slide stops playing if it is hidden, and resumes playing at Frame 1

if it is shown again.

One parameter is available only for form screens: The visible parameter indicates whether a screen is visible or

hidden at runtime. When

visible is set to true, the screen is visible at runtime. When visible is set to false,the

screen is hidden. This property does not affect the visibility of the screen in the authoring environment.
