objects that the user has not selected may appear within the borders of the
gray selection box, but only the selected objects are highlighted.
Erasing Text or Shapes 6
To erase text or shapes, a user scrubs them out with zigzag gestures.
Immediately after scrubbing, the user hears a poof sound and sees smoke
clouds cover the scrubbed objects. The smoke quickly dissipates to reveal
the scrubbed objects have disappeared.
A zigzag must go back and forth at least four times to be considered a
scrubbing gesture. The zigzag should have sharp corners, and each segment
of the zigzag should be about the same length. The zigzag can have any of
the four orientations shown in Figure 6-18.
Figure 6-18 Orientations of the scrubbing gesture
Depending on the size of the zigzag, it can erase a letter, a word, or a group
of words. Also depending on its size, one zigzag can erase a whole shape or
part of one. In addition, a single zigzag can erase text and shapes that have
been selected. Figure 6-19 shows examples of scrubbing a little and
scrubbing a lot.
