More on topic: there are many ways in which Pharo can find things that is not possible (or applicable) in other languages.
For example, there are 4 mouse clicks you can make in your image:
- left click
- right click: it shows a context menu
And then there are two clicks that I would need my laptop for to (re)figure out. One shows a “halo” around a window. The “halo” gives all kinds of options. The other one shows a context menu that allows you to figure out what objects are running with regards to the pixel you clicked on!
Because of the last click, it’s easy-ish to extend your IDE.
The last two clicks are some combination of CMD + Option + CTRL + click
