I am late to this discussion, but i would like to point out as a Scandinavian person that I do not have the same keyboard layout as most others, in the English typing, world.
This means that I cant use the same keys as the guides tells me to and it was a pain in the butt to find out how i scaled things up/down bigger/smaller also, every time I want to move something up in the air i use the 9 ) ] key which also zooms all the way out from the lot to a fixed point, which is SO FREAKING ANNOYING... This is the reason i don't use cheats like bb.moveobjects often bc its a hell to build when the screen just fly around..
I do have a laptop bought from England and it thus have an English layout, and it was a dream to build on it as everything did as intended. BUT I do not like that this keybinding option is not there, as its easy to have and if people wont use it they can just leave it be. For the people like us who NEEDS it or who want to change bc it could be way more convenient to do so, it would be nice to have the option so gameplay and building wouldn't be so hard.
Also it makes sense to move camera on W A S D and turn around on Q & E a lot of games does this, also games that are not first person shooter, great examples the sims team should look at would be some of Paradox's games like City Skylines, Surviving Mars or Stellaris or Two Point Hospital and Planet Zoo.
I really hope that if its not possible to make keybindings now, that they implement it in their next game, as i would se it as a major flaw for a game in this scale to not have that kind of small but convenient feature.. Among other missing features.
