Edit curves / ramps / other nodes with arrow keys

If you have very clear idea of what you wanna achieve with curve node, it really is a pain in butt to edit that with mouse. So curves and ramps etc. needs a way to edit the location of selected anchor point in the node with arrow keys.

Move selected anchor point with arrow keys With shift + cursor keys move it faster

This is what I'm looking for
