3.3.13 The Toggle Selection Function

Unlike the other selection functions discussed in this section, Toggle Selection is found in the Image:View menu. This command is very useful when trying to carefully position layers or selections (for examples, see any project in Chapter  7), or when trying to color-match a layer or selection edge (for an example, see Section  7.5).

The Toggle Selection command toggles on and off the visibility of a selection's Marching Ants. However, this function does not eliminate the selection. The selection is still there, it is just not visible in the image window. The Toggle Selection   feature also toggles on and off the visibility of the black-and-yellow layer boundaries in an image. This feature is also used extensively in Chapter  7.

There is a pitfall when using Toggle Selection. It is easy to forget that selection boundaries have been toggled off. This can lead to confusion, especially when a subsequent selection is made. Because selection visibility has been toggled off, the Marching Ants do not appear. I've scratched my head many times, trying to figure out why all of a sudden the GIMP no longer seemed to be working! The GIMP, of course, was working just fine. The selection is there; it just can't be seen until its visibility is toggled back on.

The Toggle Selection function is so useful that you might want to memorize its keyboard shortcut, which is C-t.
