I am using Eagle 7.6 to route a four layer board. While routing a trace, I would like to either add a via at the end of a trace or place a via mid-trace without changing the the current layer. I believe this is done with the spacebar in V8 but I don't have that.
The application is to 'pin' ground and power traces to the inner planes without a lot of futzing about. For example, all components (SMT) with a ground pad would have a little trace coming out and going straight to a via for ground.
I know I can lave the stub traces and go and drop the vias on top afterwards but this can fail if the grid changes or I am a bit clumsy.
