Selecting Frames in Keyframe Spans
Figure 8.10 Both frame-selection styles treat
protoframes identically for selection. Position the
pointer over a protoframe (top) and click to select
it (bottom).
Selecting Frames in
Keyframe Spans
Flash o ers two styles for selecting frames in
the Timeline; you set the style in Preferences.
Frame-based selection, the default style,
treats every frame individually. Span-based
selection treats frames as members of a
keyframe span—the keyframe plus any in-
between frames that follow it and display its
content. In the span-based selection style,
clicking one frame in the middle of a span
selects the entire span.
Flash CS4 introduces a new twist on the con-
cept of spans with motion-tween spans and
pose spans. No matter which selection style
you set in Preferences, there is only one way
to make selections within these spans; it’s
similar to the span-based selection but with
a few variations. (Youll learn about working
with these new types of spans in Chapters 11
and 13.)
Except where noted, the examples in this
book use Flashs default selection style,
frame-based selection.
To select unde ned frames:
To work with protoframes in either selection
style, do any of the following:
To select one protoframe, click it
(Figure 8.10).
To select two protoframes and all the
frames between them, Shift-click the
rst and last protoframes.
To select noncontiguous protoframes,

the protoframes.
e process of selecting frames that have
not been de ned works identically in
Flashs two frame-selection styles.
