82 Manipulating Images
You may occasionally (especially if the marquee is hidden) find
yourself using a tool or command that seems to have no effect... it's
probably because there's still a selection somewhere, and you're
trying to work outside the selection. In this case, just cancel the
selection.
To cancel the selection (select nothing):
• Right-click and choose Deselect, use the Select menu or press
Ctrl+D.
The opposite of selecting nothing is selecting everything:
• To select the entire active layer, press Ctrl+A, or choose Select All
from the Select menu.
For partial selection of opaque pixels, you can Ctrl-click the layer thumbnail (in
Layers tab).
If your image has multiple layers, and you switch to another layer,
the selection doesn't stay on the previous layer—it follows you to
the new active layer. This makes sense when you realize that the
selection doesn't actually include image content—like an outline
map, it just describes a region with boundaries.
