In Modo I love to select two far points in one row and then hit SHIFT+G which is selecting all points between two selected points in one row.
I know there is a SelU or SelV which are selecting a whole row but do you know something similar that could select all points between two selected points (in one row U or V only)?
I see many similarities between editing surface points and polygon vertices so that’s why I`m asking about polygonal tools for surfacing.
Don`t be mad at me that I always talk about Modo tools 
Cheers and happy Friday!!!
