The title says it all. This is so incredibly, unbearably annoying.
mesh.loop_select doesn't work now... and I can't figure out that they've made it into. Even when reset to default settings I can no longer loop select... so what's up here?
If you mean edge loop then it's just alt+right click, I also found out that if your edges aren't truly connected, Blender won't count them as full edge loops. as you said, SUPER annoying. I'll try to help out if I misinterpreted what you meant.
