The contextual menu options for functions in the Call Graph view are:

Callers

Use the arrow to the right of this contextual menu option for a complete list of all of the functions that called the selected function. Choosing a function from this list selects it in the hierarchy. If the function is the root function, the Call Graph view grays out this menu option.

Callees

This menu option works identically to the Callers menu option, only it contains a selectable list of functions that are called by the selected function. If the selected function does not call any functions, the Call Graph view grays out this menu option.

Select Callers

Selects every function that called the selected functions.

Select Caller Tree

Selects the chain of functions that led to the call of the selected functions.

Select Callers and Callees

Selects any function that called or was called by the selected functions.

Select Caller Tree and Callee Tree

Selects the chain of functions that led to call of the selected functions and every descendent of the selected functions.

Select in...

There are four Select in... contextual menu options. Each opens a report view with the current function selected in the new view.

Edit Source

Opens the file that contains the selected function in your default code editor.
