206 Notebooks and DocumentsNotice that the alias for \@VerticalBarD is Esc â| Esc, while the alias for the somewhat morecommon \@VerticalSeparatorD is Esc | Esc. Mathematica often gives similar-looking characterssimilar aliases; it is a general convention that the aliases for the less commonly usedcharacters are distinguished by having spaces at the beginning.Esc nnn EscEsc â nnn EscEsc .nnn EscEsc ,nnn Escbuilt-in alias for a common characterbuilt-in alias for similar but less common characteralias globally defined in a Mathematica sessionalias defined in a specific notebookConventions for special character aliases.The notebook front end for Mathematica often allows you to set up your own aliases for specialcharacters. If you want to, you can overwrite the built-in aliases. But the convention is to usealiases that begin with a dot or comma.Note that whatever aliases you may use to enter special characters, the full names of thecharacters will always be used when the characters are stored in files.Names of Symbols and Mathematical ObjectsMathematica by default interprets any sequence of letters or letter-like forms as the name of asymbol.All these are treated by Mathematica as symbols.In[1]:= 8x, Sa, R, , ¡, —ABC, ‡X, m…n
