What's the approved way of doing this, now? I guess if I want to replace an existing binding, I can just redefine it in cfg_ion.lua, but I'd like to remove a binding or two.
Specifically, I never use ion's "edit file" F5 binding, so I'd like to remove it (there's an emacs mode that suggests F5, and that seems OK to me, except that ion grabs it). Previously I just copied cfg_bindings.lua and edited it, but that never felt right, and I don't want to copy and edit cfg_ioncore.lua and keep that up to date.
