If rule selection is set to automatic, the routing rules such as trace width, trace clearance class and via rule are defined by the net class of the current net, if it is set to manual, the routing rules are defined by the settings in the Manual Rules window.
If the new trace gets near to a not yet connected item of the same net on the same layer, the connection will be completed automatically. After completion the IDE will return to the state before routing.
change layerTo change to a different layer. The corresponding via will be selected from the selected via rule in the following way. The vias in the via rules will be tried from top to bottom, if they contain the old and the new layer, and if inserting would be possible without clearance violations. The first via found in this way will be inserted. Shortcuts are the number keys 1-9 and the keys "+" and "-". With "+" you can change to the next bigger layer and with "-" to the next smaller layer.
end route
The routing will be finished and the IDE changes back to the previous state. Shortcut is the left mouse button.
cancel route

generate snapshot

insert
A trace will be inserted from the previous insert position to the current position and then be optimized depending on the settings for the pull tight region in the Route Parameter window.
done
The program returns to the state before routing. Shortcut is the Esc-key.
