grow selected edged limited to a loop and/or ring blender noob here(a month), was wondering if there is any way(or if there's an addon) to grow a selected edge along a loop or a ring.  this is a feature in 3ds max that i always use.  i know you can create a selection between two selected edges by holding ctrl.  what i'm looking for is a way to grow/shrink the selection along an edge loop or a ring.  Thanks!
EDIT: here's a gif of what i'm talking about:  https://imgur.com/a/ADG6aR5
I'm not sure, if I understood you right. Is this, what you are looking for:
You may select an edge-loop by holding down Alt while selecting an edge.
You may select an edge-ring by holding down Ctrl-Alt while selecting an edge.
The same works for face-loops in face selection mode.
