Question about hotkeys.

[Dinner]

Which hot keys do I press to make my workers build roads and nothing but roads? Is there a different one for railroads?

[vmxa1]

shift R -build rr
ctrl shift R - build rr to
R -build road
ctrl-r -build road to

[Willem]

You can also hit Ctrl-N, IIRC, and your workers will only build your trade network, meaning roads connecting your cities and resources, with connections to other civs.

Thank you gentlemen.
