Issue on how to switch layer and place via without a middle mouse button on a Mac OS.

Question

Hello,

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?

Regards

Niklas

Regards Niklas Search for ASSIGN in the HELP It demonstrates what you should do The command you will need to assign is LAYER (see HELP again) On a WINDOWS PC to have the F1 and F2 keys to do what you ask I would type into the command line the following: ASSIGN F1 LAYER 1 ASSIGN F2 LAYER 16 The via is placed where the layer change happens (the place you need a via) but it won't be where your mouse pointer is currently as the click that will trigger the via is the one that confirms the first segment of routing on the new layer (makes sense). The via is place retrospectively. Place the two command lines you decide on in your eagle.scr file in the BRD: section. That way that functioanity will always be available HTH Warren -- Viewed / responded via the newsgroup at news.cadsoft.de
