Hi Edouardo,

You can get the vertical bars standing for the absolute value of an 
expression either by wrapping the whole expression with 
*TraditionalForm* or by using the short-cut keyboard sequences of 
characters describe in

http://documents.wolfram.com/mathematica/book/LeftBracketingBar
http://documents.wolfram.com/mathematica/book/RightBracketingBar

In[1]:=
2\[Pi]+Abs[-x]//TraditionalForm

Out[1]//TraditionalForm=
\[LeftBracketingBar]x\[RightBracketingBar]+2 \[Pi]

In[2]:=
% /. x -> -2*Pi

Out[2]=
4*Pi

Best regards,
