This command is usually grayed out. It becomes active if you use the Fill
function or the Blend tool, or if you apply some filters.
It allows you to modify the paint mode and opacity of the
last drawable operation (Fill, Blend, Filter) by
creating a blend between the current state of the layer and the previous
state. It performs the following operations: copy the active drawable,
undo the last action, paste the copy as a new layer, set its
“Opacity”, and merge both new layer and previously active
drawable.

This command brings up a dialog window:
-
Mode
-
This drop-down list allows you to choose a
Layer merge mode.
-
Opacity
-
This slider value is initially set to the opacity of the color
you used with the Fill or Blend tool, which corresponds to
the current state. Lowering the opacity to 0 changes the drawable
to its previous state. Intermediate values produce a mixture of
the two according to the mode you have chosen. The effect of
this setting is visible in real time in the image, but you have
to click on the Fade button to validate
it.
