How to make use of the mu symbol μ in Home View

[tcab]

How can the μ symbol in the Prime be used in Home view?

In the Casio calculator referred to in this thread there is a screenshot from a video where μ is interpreted as 10ᴇ−6 and Dave seems quite excited about the usefulness of that, for electronic circuit calculation purposes. I am aware that this symbol can mean many things not just the SI prefix micro-, which represents one millionth, or 10−6.

So perhaps that is the answer, that the Prime doesn't attach any meaning to this symbol. Thus when I try anything with μ in Home view I get a syntax error. E.g. μ or 6μ or 6*μ though I do seem to be able to enter these expressions in CAS view.

To further complicate the issue, let look at unit conversions. Under Units/Prefixes there is another μ except it has a smaller, lighter font? And when I type 1_(µ) I also get a syntax error whereas I can type 1_(cm) on a line by itself and not get an error.
