Selecting items on continuous forms - solved?

This one worried me for a while. Most of the suggestions involved:

# Having a Yes/No field in the table - not possible if the
recordset is not live and useless for multiuser anyway.

# Using a temp table or 3rd party grid control - too much hassle.

So I tried the following for when there are not too many items. If
there were more, I'd look at an alternative to the collection Csel.

The recordset is read-only.
The selections are kept in a local collection Csel, which simply
Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/information-technology/12822-selecting-items-on-continuous-forms-solved.html
contains the IDs of the selected records.

Put a checkbox on the form as a calculated control, sourced from a
function passing the record ID to look up Csel. If the item exists
in Csel, the value passed is true, else false.
Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=12822

Trap the Mousedown event for the checkbox (the click event won't
fire, coz it's readonly). If the current record's ID is in Csel,
remove it. If not, add it. Then do a Me.Recalc.

Seems to work OK.
