Update 01.game_setup.rst key binding on Mac

[3mdistal]

I noticed while building my first game that grid snapping is also the ctrl key on macOS.

If it's the same, we don't need to put it in parentheses at all. But this may actually be a bug in the editor, if the key binding was intended to be Cmd on macOS.

That's what I wondered, too, about the bug. Unfortunately, I don't have enough expertise with Godot at the moment to be able to tell. I would say, though, that ctrl is generally a better binding on Mac, so that other programs don't interfere.

If this is a possible bug in the editor, does it belong here? A bug ticket would have to be created and depending on the resolution then we can re-open this ticket.

Can someone on Mac confirm whether you use CMD or CTRL for grid snapping? re: #6482

It's CTRL (hardcoded to CTRL in various canvas editor places - https://github.com/godotengine/godot/blob/8c729f0f34a92b92a1a8204e1d56b6ad05cfd27b/editor/plugins/canvas_item_editor_plugin.cpp#L352). But probably should be changed to CMD since CTRL+click is right click on macOS, so it's only usable if you click first and ten press CTRL, otherwise it will open popup menu.

I think this be CMD I had one to change all those problem but I forgot to update since 4.0 I need to remove some rename that breaks compatibility #71905. After removing the rename I will recheck every type ctrl is used to determine whether it should be removed or not.
I think I was unsure at the time whether to include snapping in it but now that I rethink about it it is obvious it should be changed

Rebased and edited to remove the invalid keybinding mention for now until we fix that.

Thanks for contributing, and congrats on your first merged docs contribution! Sorry this has been sitting for so long, thats unfortunately due to a mixture of us lacking Mac contributors and the 4.0 backlog. :)
