Hey radioactivepeanutalt,
You're in luck because that option already exists. Multiple hacks or commands just need to be separated with a semicolon (;
).
The default keybind for B already uses this syntax to toggle both FastBreak and FastPlace at once. The code for that is simply FastPlace;FastBreak
. Similarly, you can set a custom keybind for FastPlace;SafeWalk
that will toggle those two hacks instead.
Hope this helps!
