Globally use "final" and "var" modifiers in 'Introduce variable'

When using the introduce variable refactoring technique, a small dialog pops-up with checkboxes on whether to declare the variable as `final` and `var`.  

To select any of these two options, I have to use the mouse.  

Is there any keyboard shortcut to check these two checkboxes via the keyboard? Or alternatively, is there any setting to automatically introduce local variables as `final var`? 

Thank you in advance
