Just to clarify, when I right-click on something, I get a pull down menu similar to the Windows menu I included above. In Windows, I can press the key that is underlined and that command will be entered. Can the Mac OS do the same thing?
For example, right-clicking on almost anything gives me a menu that has Open as the first command. If this were Windows, I could just press the "o" key and the Open command would be executed. This is what I'm looking for.
