I am trying to understand how a particular package is working and I don’t know how to find the definitions of some functions. I can Ctrl click some functions to go to the definitions but others I don’t know how to reach, usually functions used within defined functions in packages.

For example how can I reach the definitions of the functions handle_complex() or

make_pdesys_compatible() from the function excerpt shown?

```
function SciMLBase.symbolic_discretize(pdesys::PDESystem, discretization::AbstractDiscretization)
t = get_time(discretization)
pdesys, complexmap = handle_complex(pdesys)
cardinalize_eqs!(pdesys)
pdesys, replaced_vars = make_pdesys_compatible(pdesys)
```
