lemme rephrase...
what keywords should I research to find more about the use/features/options of the ":#:#" convention??
e.g. does that feature have a name?!
You know variable expansion covers how the shell interprets variables, but if people don't know the term "expansion", they might query for the wrong things. You get my point...
I've read lots of documentation and have never come across that, I'm thoroughly familiar with sed, my awk knowledge needs to catch up though.
Dude, I really appreciate this technique. It'll be very helpful when extracting certain portions of uniformly-formatted strings and storing to variables.
So if you know of a particular name (keyword) for that string:#:# technique, I'd appreciate it.

strstr
STRSTR(3) Linux Programmer's Manual STRSTR(3)
NAME
strstr - locate a substring
SYNOPSIS
#include <string.h>
char *strstr(const char *haystack, const char *needle);
DESCRIPTION
The strstr() function finds the first occurrence of the substring needle in the string haystack. The terminating ` ' characters are not
compared.
RETURN VALUE
The strstr() function returns a pointer to the beginning of the substring, or NULL if the substring is not found.
BUGS
Early versions of Linux libc (like 4.5.26) would not allow an empty argument. Later versions (like 4.6.27) work correctly, and return
haystack when needle is empty.
