how to set env config ( smali code not showed)

[mehrdad-data]

i really sorry for my noob question

I download GDA4.10 and open crackme file.
in your wiki help said press M to edit smali code.
i other page said press F5 to show smali code.
when i press F5 nothing happend and smali code not showed.
I think I must set Env config but not found help how to do it.
I use Windows 7 64bit.

thanks a lot

No set any Env, make sure your cursor in code and press F5. or switch your keyboard input as English.
