How to "find usages" of dictionary element in Pycharm?

Question

When using Pycharm, I rely a lot on the "find usages" feature.

This allows me to position the cursor on a variable and get automatically to that place where the variable is assigned for the first time. Using it at that place again, I can find all following usages of that variable.

Unfortunately, this is only working for variables, but not for dictionary elements:

Is there any workaround or alternative for this?

The code relies heavily on dictionary elements, so I would even use a different IDE... . And I know it gets even more complicated, once the dictionary is initialized via xyz2 = {'a': 1, 'b': 2, 'c': 3} .

For the sake of completeness, here is the code I used:

abc = 3

xyz2 = { } # was: xyz2 = []
xyz2['a'] = 1
xyz2['b'] = 2
xyz2['c'] = 3

xyz2 ['a'] = 15
xyz2['a'] = 15
xyz2['b'] = 15
abc = xyz2['a']
