How do I export my game?

I am having trouble editing the properies of an object to update all the instances of that object project wide. I am making a metroidvania so this sort of feature is really important. Construct2 had the ability. I am sure Construct3 has it but it might not work the same way as it use to? Can anyone enlighten me as to how to do this? Example below of what I am seeing in my own project.

Turns out you have to -right click- the object in the projects bar to bring up the option to "Select all in project". Hope this helps anyone else switching from C2 to C3 or just in general. :)
