I would like to place the same building multiple times. For apartments, this is enabled by default, but for other buildings, I have to go through the build menu again.
- Last Constructed Building: \
- Cycle between building variants (e.g. different types of farms): [ and ]
- Rotate camera: Alt + Arrow keys
- Zoom in and out: Page Up and Page Down
- Rotate buildings: < and >
- Demolish: Delete
- Last On-Screen Notification: F2
- Open Almanac: F1
- Road: R
- Select Avatar: Backspace
As a preliminary answer, several buildings are accessible via a keyboard shortcut. For instance, roads can be selected by pressing 'R', garages by 'G'.
