 ### Using Functions/Methods/Functors/Lambdas as Actions {#FunctionsAsActions}
 
 If the built-in actions don't suit you, you can use an existing callable
-(function, `std::function`, method, functor, lambda as an action.

 ### Invoking a Function/Method/Functor/Lambda/Callback Without Arguments
 
-`Invoke()` is very useful for doing actions that are more complex. It passes the
-mock function's arguments to the function, etc being invoked such that the
-callee has the full context of the call to work with. If the invoked function is
-not interested in some or all of the arguments, it can simply ignore them.

 Yet, a common pattern is that a test author wants to invoke a function without
-the arguments of the mock function. `Invoke()` allows her to do that using a
-wrapper function that throws away the arguments before invoking an underlining
-nullary function. Needless to say, this can be tedious and obscures the intent
