@Mr.Wizard (per your mention of not having looked at the Notation` internals in a while) all it does is coerce the boxes to a string representation (in the case of Subscripts this is x\[UnderBracket]Subscript\[UnderBracket]*) and then applies MakeBoxes and MakeExpression in the way one would expect. This means you can easily clear all such variables via Clear@"x\[UnderBracket]Subscript\[UnderBracket]*".

@H.R. If you use the TagSet method the rule is attached to e.g. a, and if a is in the Global context ClearAll["Global*"] will clear that rule.

Is there any way that we could clear by ClearAll["Global*"]?

@Manuel--Moe--G That would work but usually it is better to use e.g. a[5] which makes conversion in either direction much simpler and faster. However there are places (like Module) that actual Symbols are needed. Also, I haven't looked at the internals of the Notation palette in some years but I seem to recall that the use of Symbolize is performing this kind of translation itself, such that Symbols are used in place of Subscripts during computation, then formatted again as Subscripts for output, so look at that before you "reinvent the wheel" as it were.

is it good MMA form to convert subscript as quickly as possible to something like a5 and then at the last step for output output the result with a subscript, so do the majority of manipulations with identifiers like a5?

Namely: a<sub>3</sub> = "lion"; where "<sub>3</sub> should be an actual subscript, typed in the Mathematica Front End by first typing Ctrl _ . | |
