How can I quickly open declaration of any variable, function name, macro, or header file from within Editor?

To quickly open declaration of any variable, function name, macro or header file from within Editor, press the Ctrl key and click the text. Alternatively, place the mouse cursor on the text and perform either of the following:

press F3,
right-click and select Open Declaration (as the figure, Open Declaration listed below shows), or
select Navigate > Open Declaration from the IDE menu bar ( as the figure, Navigate Menu listed below shows).

This will open the logical file associated with the selected text. For example, for a header file include, the header file will open. For variables, the file containing the definition or declaration of the variable will open.
