 So you just want to slide, not a problem. Edge slide lets you left click to slide an edge along a surface. If you're on edge, you'll target a single edge. If you're an edge loop, you can target the whole loop around the object. And if you want, you can hold shift in order to move the edge while you slide it. And as usual, edge loop partial is the same as edge loop, but it stops affecting points that are only connected to three edges. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
