This article is about the first Commander Keen level editor. For Andrew Durdin's level editor that was originally know as KeenEdit, see KeenWright.
KeenEdit is the first fan-created Commander Keen level editor to be published on the internet and used to create many of the oldest Commander Keen fan levels.
It is a DOS-based editor created by Jeremy Haubold and was intended to produce and modify Commander Keen 1 levels, though due to their similar nature it is also a fairly functional editor for Commander Keens 2 and 3. Unlike later level editors which used captured level tile graphics, KeenEdit uses ASCII characters to represent tiles.
The newest version of KeenEdit, version 1.2, was released in 1996.
