Now that we’re on the subject anyway, if you know what blend mode you want to use, you can use the direct hotkeys:
[b]Normal: shift+alt+N
Dissolve: shift+alt+I
Darken: shift+alt+K
Multiply: shift+alt+M
Color Burn: shift+alt+B
Linear Burn: shift+alt+A
[/b]
[b]Lighten: shift+alt+G
Screen: shift+alt+S
Color Dodge: shift+alt+D
Linear Dodge: shift+alt+w
Overlay: shift+alt+O
Soft Light: shift+alt+F
Hard Light: shift+alt+H
Vivid Light: shift+alt+V
Linear Light: shift+alt+J
pin Light: shift+alt+Z
Difference: shift+alt+E
Exclusion: shift+alt+X
Hue: shift+alt+U
Saturation: shift+alt+T
Color: shift+alt+C
Luminosity: shift+alt+Y

If you have the brush tool selected, you’ll be changing the brush blend mode, if you have the move tool selected you’ll be changing the layer blend mode.
