From RevDeBug menu you can open very useful window: View symbols (Symbols
view). It shows all variables and their values used in the current scope as visible by the currently
viewed application state.
Clicking on the two arrows symbol displays a list of all the recorded values for this variable, with the option
to jump to the state (i.e. a moment in time) where it was set or read.
Variable values are also shown within overlays that RevDeBug adds to the source code
view, so you can see what they were in that particular moment in time
The overlay hints are always displayed above the corresponding instructions. In the example above,
the variable ’_sharedNumber’ has a value of ‘-1’ and ‘testFromat’ got value ‘-2’.
