Rethink problematic macros

[tmedwards]

Rethink—rework, repurpose, or remove—problematic macros.

• [ ] <<actions>> – Either confusing or a poor fit for what most want to do with it.
• [ ] <<back>> – Name is confusing to some. Possibly rename to <<undo>>?
• [ ] <<choice>> – Either confusing or a poor fit for what most want to do with it.
• [ ] <<return>> – Name is confusing to some and doesn't currently work for long return cases.
• [ ] <<silently>> – Macro is fine, I just dislike the name. Possibly rename to <<silent>>?
