But there’s an easier way to get from the editor where you’re writing code to the wellspring of knowledge in the documentation. Close the Organizer and return to your DateList project.

In main.m, find the line that includes [dateList addObject:now]. Hold down the Option key and click on addObject:. The Quick Help window will appear with the information about that method:

Notice that there are links in the Quick Help window. If you click a link, it will open the appropriate documentation in the Organizer. Handy, right?

If you want to see that Quick Help all the time, you can open it as a pane in Xcode.

In the upper-right corner of the Xcode window, find a segmented control called View that looks like and indicates Xcode’s lefthand, bottom, and righthand panes. Selecting and de-selecting these buttons will hide and show the respective panes.
