1. add global block
2. fill it with content.
3. add the code $GLOBAL_ANYWORD$ to the templates you want that block to be shown in.
Don't forget about the feature "Quick substitution of template parts" and try to examine the feature "Templates builder" in Design tab of the Control Panel.

I’ve noticed the global block $GLOBAL_SOANDSO$ will not run inside $CONTENT$ area.

You are right. Global blocks work in templates only

Just 10 global blocks?

10 is the limit, you can't create more global blocks.
