I was just wondering if there is a way I can move current node while creating a path? It's basically similar as changing the previous node position with arrow keys but I'd like to change the current one. People who are familiar with Illustrator.. when you're creating a path and draging bezier curve handles for the current node, you can hit space to lock the current handle position and move the node. I'm not sure if you get what I mean..

Forum/google search didn't come up with any meaningful responses and manual only talked about moving the previous node created hence I'm asking here.
Any ideas? Can this be done somehow in Inkscape? I find this feature helps alot when creating paths.
I'll throw in couple of images to show what I mean..
So for example on this image I've created a path with two points and I'm trying to figure out the curve I want.
But while dragging the curve handles I decided I want the current node to be in a different place so with Illustrator you can hit space to lock the curve handles and move the current point/node
Hope this makes it more clear.
