I have been using photoshop 8 for a long time but when I moved to photoshop 10 cs3 I got some problems.. in cs2 I used to fill paths and shapes with colors using shortcut (alt + enter) which doesn't work in photoshop cs3.. any idea how to do that in cs3?
Photoshop 9 is CS2 Photoshop 10 is CS3 and to answer your question, logically, it should be the same.
In CS3, to fill a shape or a path with foreground colour: ALT + Backspace. To fill it with Background colour: CTRL + Backspace. Hope, i cleared your doubt!!
