History of call commands when running a script with pdb in PyCharm

When I use Run

in PyCharm 3.4

(Windows 8.1) for this script:

if __name__ == "__main__":
x = 'lolo'
import pdb; pdb.set_trace()
print(x)

      

        
        
        
      

    

I go to Run Tool Window

where I can play with pdb

:

C:\Python27\python.exe D:/check/old/stack.py
> d:\check\old\stack.py(4)<module>()
-> print(x)
(Pdb) x
'lolo'
(Pdb) 

      

        
        
        
      

    

But I can't figure out how to call the last command / navigate the command history.
↑Or using ctrl, alt, shiftgives nothing :( The building in PyCharm Terminal or Command Prompt, the Windows / the Git Bash works just as expected.
Maybe there is some configuration Run

that I am missing?
