Can't edit the wiki and I have a change to make.

I noticed on the macro page that the value for “. matches newline” in the Regexp section is not documented. I believe it should be 1024.

I think this is a more direct link to what you are referring to.

I also think that you are correct, although probably a lot of Regular expression search mode users ignore the . matches newline checkbox and use instead (?s) or (?-s) at the start of their regular expression. Doing this makes unnecessary the need to know the 1024 mask value for the lParam of the 1702 message.

BTW:

(?s) at the start of Find what means effectively . matches newline checkbox ticked
(?-s) at the start of Find what means effectively . matches newline checkbox cleared

and:

. matches newline checkbox ticked means the 1024 mask value is used
. matches newline checkbox cleared means the 1024 mask value is not used
