Move a part or connection around
Click a part to rotate it 90 degrees
This command can do anything, and once selected, will apply to anything you click. For example, if I wanted to chagne the width of all my routes, I would say "change width", then select the width I want, and now every route I click will change to that width.
Write some text, NOT attached to any part of connection
Commands can act on multiple parts/connections at once. Here is how you group a command:
Enter the command you would like to group (for example: "move")
Enter the group command (type "group")
Click and drag to highlight the parts/connections, and release
Right-click one of the highlighted parts, and a menu will appear next to your mouse
Click your grouped command (for example: "Move: Group")
Load all libraries, where you can pick a new part to add
Click a part or a connection to delete
Draw electrical connection between two pins
Copy a part or connection by clicking it
Give a part or connection a name
Display the "name" of a part or connection (most useful for connections)
Draw the traces that will become phyical copper traces. Turn those thing yellow "unrouted" lines to real traces, either on the Top (red) or Bottom (blue) layer.
Remove a trace that was drawn with the "route" command. This does not delete a connection, but only removes the trace you drew for it.
