Which term describes a symbol used temporarily as a substitute for something that is not known or that must remain generic?

Explanation:
A placeholder is a symbol used to stand in for something that isn’t known yet or that should remain generic. It lets templates, forms, or code be created without fixing specific data, so the structure can be shown or tested before the real information is available. That makes it the best fit for describing something temporary and substitutive. The other terms don’t match: a ruler measures, a screen shot captures the display, and a slide is a page in a presentation.
