Hi Doug,

for such cases I use this tmcommand:
Input: selection or document
Ouptut: new doc
Command:
#!/usr/bin/perl -w
#!/usr/bin/perl -w

$cnt=1;
$inc=1;

while(<>) {
	if(m/^\\i\((\d+)\s*,\s*(\d+)\)$/) {
		$cnt=$1;
		$inc=$2;
		next;
	}
	while(s/\\i/$cnt/) {$cnt+=$inc;}
	print;
}
Example text:
Hello, this is a test.
\i(2,5)
Here my \i. item followed by item \i.
Furthermore here is my \i. item.


Then you get:
Hello, this is a test.
Here my 2. item followed by item 7.
Furthermore here is my 12. item.


If you do not set up \i(a,b) it simply starts at 1 incremented by 1.

Hopefully it helps.
