Change first space in each paragraph to a tab

Does anyone have a simple macro that will change the first space in
each paragraph to a tab? Greatly appreciate some help with this.

Find and Replace will do this. Search for ^p[space], replace with ^p^t.

Thanks, Jezebel, but this will only work if the first character of each
paragraph is a space. I have no way of knowing how many characters
occur before the first space in each paragraph.

Sorry, I assumed you meant leading space. For the cases where there are 
intervening characters, check the 'Use wildcards' checkbox and use

Search for: (^013[! ]{1,})[space]
Replace with: \1^009

Thanks, Jezebel, but I'm still having trouble, probably because I
have little undertanding of the symbols used. With 'Use wildcards'
checked and ignoring the asterisks, I've tried these combinations for
find, but none of them works:
*(^013[! ]{1,})[space]*
*(^013[! ]{1,})[ ]*
*(^013[! ]{1,}) *

[space] just means a single space, no brackets, so your third option looks 
right. What it all means:

^013 is a paragraph mark
[! ] means "not space"
{1,} means one or more of the preceding matching -- in this case [! ]{1,} 
means one or more non-spaces
Tbe brackets are for grouping, to match up with the \1 in the replace 
string.

So all combined, what you're searching for is "paragraph mark followed by 
one or more non-spaces followed by a space". You're replacing with "whatever 
was matched by the contents of the brackets, plus a tab"

I tested it -- it does work.

Thanks again , Jezebel. Slowly getting there. Seems like I have a
problem within a problem. I believe the reason nothing was happening
was because I was using the Czech version of Word. Let's leave that
aside for a moment.

When  I use the American version of Word, the Find works, but not as I
want it to. The wild card expression selects a paragraph mark and the
text in the next line up to and including the first space. I'm trying
to find the first space in each line. Example:
abc def ghi
a bcd fgh i
ab cdfg hi
line 1, needs selection of the space between c and d
line 2, needs selection of the space between a and b
line 3, needs selection of the space between b and c

I tried reading the help on wild cards, but it was beyond me. Really
needs an expert.

The method Jezebel provide will work for all paragraphs except
paragraph 1.  That one you will need to do manually.  If it isn't
working, then the units that you are called paragraphs (i.e., lines)
are not in fact individual paragraphs.

Yes, it finds the paragraph mark. That's OK: it's just another character, 
and it gets replaced.

Brian Holfield was telling us:
Brian Holfield nous racontait que :


Replace the "," by a ";"
The semi-colon is probably the list delimiter in Czech, as it is in many 
European version of Windows.

Oops! Yes, It works. I shot myself in the foot by not understanding the
code and going step by step. When I saw so much selected by the find my
reaction was: Whoa, I don't want to replace all that with a tab. But,
now I see that the replace code takes care of that nicely. Thanks for
being so patient with me, Jezebel, and thanks for solving a problem
that was holding me up.

Yes, it works nicely, Greg. My paragraphs were OK, it was my mental
attitude that tripped me up - see reply to Jezebel

Thanks for the suggestion, Jean-Guy. That's probably the right
direction, but it needs something in addition to changing , to ;.
