Check your preference settings in Windows->Preferences->C++->Editor->Hovers
I would suggest (just my personal opinion):
Combined Hover => Alt
Debugger       => no key defined
Source         => Ctrl

Then you can hover with your mouse over a variable during debugging and a 
tooltip will show its value. If you press Ctrl and then hover you will see 
the source code (i.e. definition of the variable etc.). If you can use 
Alt+mouse the type of hover depends on the situation (debugging or source 
or something else).

But beware that hovering does not work well with member variables e.g. 
pointer->variable. You will just see the pointer address. See 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=200418 (please add your 
vote, I am waiting for this bug to be fixed for many years!).
