I have nothing interesting to do, so here we go:
- A = fully automate worker
- Shift-A = automate without altering prexisting improvements
- Shift-I = automate, this city only
- Shift-P = automate, clean up pollution only
- Shift-F = automate, clear forests only
- Shift-J = automate, clear jungle only
- B = build colony when on a resource
- Ctrl-F = build fortress
- M = build mine
- Shift-R = build railroad
- Ctrl-Shift-R = build railroad to...
- R = build road
- Ctrl-R = build road to...
- Ctrl-B = build road to, then build colony at...
- Ctrl-N = build trade network roads
- Shift-C = clean up pollution
- I = irrigate
- Ctrl-I = irrigate to nearest city
- B = join city population as one citizen (workers in a city)
N = plant forest
and last but not least,
- J = group all workers in a tile and move them together.
