Indeed, a very bad hack. Nevertheless, often a useful one.

Yep. Mike Solomon has an excellent guide:

In brief, InputManagers can have their code automatically loaded into 
all
Cocoa applications. This can be all sorts of useful if you're trying to
globally override some AppKit behavior. If you're just trying to 
override
a behavior in one program, you may want to take a look at Unsanity's 
APE,
which does some similar things on a per-application basis.
