Need one space default between sentences in Word. Possible?
There's no such thing as a default for spaces between sentences, whether
one, two, or otherwise. What you type is what you'll get.
There is, however, a setting for the grammar checker that will flag the
"wrong" number of spaces as an error, which you'll have to correct manually.
In Tools > Options > Spelling & Grammar, click the Settings button and
select the desired number for "Spaces required between sentences". If you
want the green squigglies to appear, make sure you have enabled "Check
grammar as you type".
You can run a Replace that searches for a period followed by two spaces, and
changes it to a period followed by one space; then click Replace All. You
can record this as a macro, and assign it to a button or keystroke.
