I use Eagle 6.2 and I use a MAC OS.
I want to be able to switch between layers when routing pcb connection wiring and automaticly get a via where I happens to have my mouse pointer pointing.
When I google this I have found out that I use the middle mouse button to do this.
Unfortunately there is no middle mouse button on my iMac mouse.
So, I was hoping to be able to use some shortcut key for this purpose.
If I go under the menu Options I can select Assign and that seams like a solution.
But I do not know what commands I should use for this.
I want to press the key '1' to select the top layer and the key '2' to select the bottom layer and also place a via at the same time that I press '1' or '2'.
Can someone help me out how to do this or tell me some other smart way to do this?
