Selecting multiple things in an event's script

Is that possible? I'm doing a scene with riddles and I don't wanna have to copy down each individual moment for when you guess wrong into every single wrong answer.

I don't understand what you are looking for.

When you're setting the troops to appear on a map  if you hit CTRL and click on multiple troops there you select multiple so you can copy multiple to different maps. I want to know how to copy multiple things at once in an event.

Click on something in the event contents, then shift-click on the end of the section you want to copy, then hit ctrl-C.

If you want to copy a whole event page, just click the button that says "Copy Event Page" at the top of the event.
