During the process of documenting a symbol, it may be necessary for you to jump to either its definition or implementation. You can do this by selecting the Symbol(s) symbol command in the Show menu of the Documentation Editor. The Choose Symbol dialog appears. You can then jump to either the symbol's definition or implementation from this dialog.
When you are in the source or header file, you can jump back to the corresponding documentation file by selecting the symbol and then choosing the Show Documentation of symbol command in the Info menu of the Source Editor.
