The suggestion to look on the Adobe site lead to the solution. This is the best answer from Adobe:
Solution 1: Bypass the keys' default OS-level commands.
Note: Use this solution only if your keyboard has a key labeled Fn.
To make Mac OS interpret F1, F2, and so forth as function keys instead of as OS-level command keys, hold down the Fn key when you press a function key. For example, in an Adobe application that uses F1 as a keyboard shortcut, hold down Fn and press F1.
You can also make Mac OS interpret F1, F2, and so forth as function keys by default. (If you do so, then you can still perform those keys' OS-level commands by holding the Fn key when you press them.) If you want to make this change, then do the following:
1. Choose Apple Menu > System Preferences.
2. Click Keyboard & Mouse.
3. Click the Keyboard tab.
4. Select the option Use All F1, F2, Etc. Keys As Standard Function Keys.
5. Quit System Preferences.
