I have been using Blender for quite a long time and I just want to make sure that there isn't a better way of selecting edges, that I might not be aware of. It is so cumbersome to have to click every single edge when I don't want to select an entire edge loop but a portion of one instead. I was wondering if there is some way in to specify a start edge and an end edge and then be able to auto select every edge in between?
While this is not what this feature is intended for, on straight or simple meshes you can use Shortest Path from the Select menu with the two points selected or by selecting the starting point then selecting the end point while holding Ctrl. You can also incrementally add to your selection by holding Ctrl.
