Vi mode: Vi mode for Drscheme

by Jon Rafkind (rafkind at cs dot utah dot edu)

This package provides a mode for Drscheme that emulates some Vi commands. This package is in beta mode, it doesn’t have a lot of features and probably has some bugs. Feedback and bug reports is more than welcome!

1 Install

Execute the following line in Drscheme or Mzscheme "(require kazzmir/vi/tool)"

Then restart Drscheme.
