Amusingly, for a long time, emacs has effectively been this, but with a fuzzy search tool. Very common to just bring up the command minibar and start typing words looking for relevant things.

Going back, many old machines were like this. They all had some form of "apropos" command that we seem to have completely forgotten about as things got bigger. Indeed, the idea of man pages and the like seemed to get skipped out on with dos, such that windows also didn't really have it ingrained heavily. The docs were almost certainly there, but they were often specific in formatting to each program? (Or is my memory just off?)
