KeithB told you, in their post above

in CAS, you can use purge(). You can also:

CAS — Vars — CAS — All — <var> then backspace to delete

memory manager (Shift B) — CAS Vars; select, then delete or backspace.


In Home, viewed with:
Home — Vars — User — User Variables — <var>; backspace to delete

memory manager Shift B — User Variables
scroll down for lower-case variables
select, then Delete or backspace
may also be deleted with function DelHVars()
