Change feedback node direction by pressing TAB when placing

[Stefo]

I've just noticed that when i use feedback node (mostly in FPGA), it would be very useful to be able to change direction while placing the node to block diagram (for example by pressing TAB). 

It is very simple implementation, and it would save time, because people wouldn't have to click on the node and selectinch "Change Direction".

Good idea
