Hovering and Debugging

Join For Freeeclipse provides in the editor view great tool tips (called ‘hovers’) which shows what is behind a macro: i can move my mouse over it, and it shows me the content behind it:
but if i’m debugging, i get “no value available” :
obviously, the debugger queries the value of that macro, and as there is no variable with that name, there is no value. makes sense. but: how can i see the macro value while debugging?
the solution is to configure different hover keys in the preferences (menu window > preferences > c/c++ > editor > hovers ):
the above dialog shows as well that there are different hovers available. by default, the ‘combined hover’ is used. and it is using the debugger hover, which cannot provide a value, thus the ‘no value available’ result. the hover preferences has as well the possibility to assign a modifier key: with this, a selected hover can be used.
and indeed: if i use the ‘shift’ key pressed while hovering in the debugger, i get what i want
:
happy hovering
