The Align tool is useful to align the image layers with various
image objects. When this tool is selected, the mouse pointer turns
to a small hand. By clicking on an element of a layer in the
image, you choose the layer which will be moved (with Shift
+ click, you can choose several layers to be aligned);
this focalised layer has small squares in corners.
Various buttons in the dialog allow you to select how the layer
will be moved. And you can select the image object (other layer,
selection, path...) the selected layer will be aligned on. This
object is called target.

Tip |
|
Sometimes it's easier to choose multiple layers using
rubber-banding: click somewhere outside an imaginary rectangular
region covering the layers you want to choose. Then drag out
that region by moving the pointer, and release the mouse button.
Now every layer, which is completely inside the dragged
rectangle, is selected.
Note that now there is no target “first item” the
selected layers can be aligned on.

Normally, tool options are displayed in a window attached under the
Toolbox as soon as you activate a tool. If they are not, you can access
them from the image menu bar through
→ → which opens the option window of the selected tool.
