I found on this link how to apply some of the usage of command prompts within Photoshop.
For example:
Control + + ( Command + + ) = Zoom in. Control + - ( Command + - ) = Zoom out.
Shift + Alt + n ( Shift + Option + n ) = Normal
Shift + Alt + i ( Shift + Option + i ) = Dissolve
Shift + Alt + k ( Shift + Option + k ) = Darken
Shift + Alt + g ( Shift + Option + g ) = Lighten
Shift + Alt + m ( Shift + Option + m ) = Multiply
Shift + Alt + o ( Shift + Option + o ) = Overlay
Shift + Alt + u ( Shift + Option + u ) = Hue
Shift + Alt + t ( Shift + Option + t ) = Saturation
Shift + Alt + y ( Shift + Option + y ) = Luminosity
Control + Shift + s ( Command + Shift + s ) = Save your work as
Control + Shift + Alt + s ( Command + Shift + Option + s ) = Save for web and devices
I can use this to in a faster manner to edit and modify pictures to my liking.
