Points can’t be unselected with the escape key when using the smoove tool.
If we can move points with the smoove tool can we select multiple points then move them? Not just lines. Moving points is sometimes more useful than moving edges.
The points selected are based on the radius entered into the VCB. The points are based on the current selection of faces/edges.
If you want to be able to control each vertex you might want to try out my Vertex Tools extension. (Not freeware though - $20, but you can try it out with all features for 30 days.)
I use a screen grab software.
It sounds like smoove isn’t the tool for what you want. Smoove means smooth move. So it selects things in a radius but moves them less the further from the center, which gives you a smooth finish.
You sound like you want to move points along a line. You can move vertices and edges just using the standard Move tool.
Although Thomthoms Vertex tools is the bees knees.
But you see, if you select something with the select tool and hit escape it remains selected.
Escape ends an action, it doesn’t deselect.
So as I said before, if you don’t preselect anything the smoove tool only selects when you click and then drops that selection when you click again. So click to select, move then click again and it deselects.
You’ll only see a gif because I use a little capture software called gifcam.
But there are many others.
