You can use TeX Macros in DrScheme 3.99.0.23 and newer!
Here is how you do it in either the editor or the REPL:
- Enter a backslash
- Enter the macro name
- Enter M:\
This is yet another delightful thing that the PLT folks have added to an already great IDE!
Here are some TeX macros (source)
- rightarrow
- sim
- equiv
- lambda
- pi
- alpha
- omega
