Created attachment 379962 [details] Added epatch_user to ebuild As key-bindings are defined in config.def.h, the user should be able to patch easily
It already uses USE=savedconfig to store config.h. Adding etpatch_user to the mix isn't going to work. Unless you suggest I replace savedconfig with epatch_user, but editing config.h and creating a patch is a lot more hassle than simply editing a single file.
FYI, it's EAPI=7 now and patching should work
