Apply all modifiers at once

Support Modeling

Hi everybody,
I’m modeling a part of a city. I have a lot of arrays for buildings’ doors and windows and I’d like to apply the modifiers in my scene all at once. Is it possible?
I noticed that if i export in a collada format I can do it, but what about inside Blender?
Thanks

As far as I can see Alt + C should do it.
