There’s oodles of them, check the controls in the options for the full list. Here’s a few that are handy early on:
- Middle click “locks” a tool tip open – so you can hover links on the tool tip. This can stack/expand to dig into details.
- V shows you your “connections” (mix of rivers, roads, harbors, that link your cities)
- Z hides “ground cover” like trees so you can see just the base terrains.
- CTRL+click (with a worker selected) on a tile within a city for a popup of everything you can do/build with that tile
- Hover over settle-able tiles (with a settler selected) to see how the borders will look for the different tiles you can settle for that city plot.
- Spacebar will fire the “pass” action for a unit (does not “exhaust” them, you can manually reactivate).
- TAB is kind of a universal “cycle” – it hops you between anything needing attention or idle.
More from the leader portrait parf of the UI:
- 1 cycles your events/and required actions for the turn (city needs to act, etc).
- 2 cycles idle growth based units (settlers, workers, scouts, etc) – prioritizes settlers > workers > others.
- 3 cycles idle military units.
- 4 cycles idle cities.
- 5 ends your turn if you have no required actions to handle, with no confirmation – probably worth avoiding until one has a feel for the orders system.
