Hi, I'm not an expert in maths, but an English teacher. I was writing some mathematical symbols with "EXE" to show my students how they should be pronounced and I saw that the symbol corresponding to "\mapsto" is the same as "\rightarrow". I also saw that "\overrightarrow" doesn't exist. I just hope this is helpful to the developers.
