Default Function of colon between table names when query in design view

I am looking at a field from a query that is in design view. Inside the
field are two field names from the same table which are separated by a colon.
For example, Old and New are both fields from tblReplace and appear like
this Old:New in design view. I believe the colon concatenates the field Old
and New into a new field when you change the query view to datasheet view.
Am I correct?

Also, in a completely separate question if you are looking at a query in
design view and there is a field in the (Field row, a table in the (Table
row, and Group By in the (Total row what function will the Group By option
perform when you change the query view to datasheet view?

If you are talking about having a field "block" with something in it like
Field: Old: New
that should be assigning an alias "OLD" for the field named NEW and should not
do any concatenating at all.

It will consolidate all the same values into one row. For instance if you had
a table with first names and last names show only the first name and GROUP By
the first names you will see one row for everyone who has the first name JOHN.

If you add the first name field again and set the Total to COUNT you would see
something like

FIrstName CountOfFirstName
JAMES_________8
JEAN__________1
JOHN__________22

If you have multiple fields and group by them, then the group by is done on
the combination of the fields.
