I wanted to change the default shortcut key to preview in browser in Dreamweaver. Mac OSX has stolen the old key F12 for dashboard, and the alternative key, opt-F12 is too hard to remember. It took me a good 30 minutes to figure out how to do it, ending up with a web search which led to the Macromedia help site.
Here’s the trick: Go to the keyboard shortcuts in the “Dreamweaver” menu. Then select the pulldown menu for “Menu Commands”. Select “Document Editing” and find “Preview in Primary Browser”. Click on it to highlight, then you can see the shortcut currently in use. Click in the press key box and press the key you want to launch the browser. Click the change button. It asked me to save my settings into a new set, then I had to go back and select the key again.
