In the VBA IDE, selecting a standard keyword (ex. MsgBox) and selecting View / Definition takes you the Object Browser for that keyword. In other words, the VBA IDE takes it's best crack at finding the keyword and presenting it in the Object Browser. (Usually, it does a good job.)
In the Visual Studio IDE, selecting a standard keyword (ex. MessageBox) and selecting View / Definition doesn't take you to the Object Browser, instead it takes you to the code where the keyword is defined. This is often useful, but it would be nice if there was a way to instruct Visual Studio to open the Object Browser and to take a crack at finding the selected keyword in object browser. Is this possible?
Using View / Definition brings you to the location within your project where you defined the variable or function so you do not go crazy looking for it. If you want the documentation for a keyword, highlight the keyword and then press PF1. Depending on how you did the initial install of Visual Studio the internal documentation will come up if you loaded it and if not the default internet browser will open up and go to the documentation on the web.
