You can also type into the calculations on the machines themselves, so if you want 133 instead of 120/min you can simply type that in and it'll tell you what the clock speed should be.
In some cases, it can actually be smart to underclock. It's exponential in that direction too, meaning machines become more power-efficient the more you underclock them.
Generally speaking, the only things you should be overclocking are resource extractors to be able to feed more production from the same nodes; overclocking production machines doesn't really make sense when you can just build more machines, space is pretty much the least limited resource in the game.
That said, there are exceptions and sometimes a little overclocking helps things balance out without weird machine counts that are hard to plan for, or if you just misplanned a space and expanding would mean tearing a lot out and redoing it
Tapping "E" will toggle between all the types of a constructable. On belts, for example, you toggle through the tiers.
So you can have just tier one belts on the hotbar, and to select tier two, three, etc. you'd just tap E the corresponding number of times after selecting "belt". You can to get to a shitload of constructables really fast with just one hotbar.
Is there like a documented list of all of these little tips? I feel like the longer I play, the more I realize just how incredible the controls actually are.
Almost all of these the game literally tells you about right there in the GUI... When you are building, you get an info bar telling you what button combinations do what. This is smart enough to even depend on what exactly you are building, so it will not tell you about R for build modes when you are building things that don't have build modes.
Another small thing not everyone knows about: when building normal hyper tubes or pipelines, you can rotate the end point vertically as well. While placing it ( hold left mouse button), you can drag the cursor up/down for elevation, but you can also use the scroll wheel to tilt the connector. This allows for more aesthetic long gradients, without having "steps" on the connectors.
I use this all the friggin time, it's such a huge time saver
Though, if it's a particularly complex build, I'll usually use Satisfactory Tools' production calculator along with Satisfactory Calculator's interactive map to plan where to source materials...
I do have a construction planner tab open in my steam overlay.
The fact that steam now remembers the tabs you had on a game-by-game basis makes it extra useful. You can close the game, and it wont appear in other games, but start up Satisfactory, and all your plans are right there.
I wish there would be a in-game production/consuming statistic. So that I can see, if I have to build more machines of type xyz. It's really annoying to use SCIM for this.
