Adobe fireworks transparent text area
How can I achieve this with Fireworks? Or what is the exact name of this technique, so I can Google it?
I know this is really old, but this technique is really useful, make a black square and text layer on top white; group them; go to live filters "other > convert to alpha", go to "adjust color > color fill" and choose your color in this case white, after that you can change the opacity as you want. The good thing about this, text is still editable just use the text tool or the alternate selection and double click the text ;).
