Some versions of grep or grep-like utilities can do this. For example, the very versatile cgrep can. Here is a sample of first extracting the string plus the trailing window, then the inversion of that operation, which effectively deletes it, both operations writing to STDOUT:
producing:
So cgrep is not very diffferent from sed when cgrep is used this way. Where it might be superior to sed is in the selection of context window limits: regular expressions and line counts (the latter as shown above) can be used to mark easily the leading and trailing boundaries of a window.
You may need to download and compile cgrep, see the URL in the code above. I have done so on 32-bit and 64-bit GNU/Linux systems.
Best wishes ... cheers, drl

echo
ECHO(1) BSD General Commands Manual ECHO(1)NAME
echo -- write arguments to the standard output
SYNOPSIS
echo [-n] [string ...]
DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline ('
') character, to the
standard output.
The following option is available:
-n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2
compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001
(``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup-
press the newline character.
Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does
not accept the -n option. Consult the builtin(1) manual page.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO builtin(1), csh(1), printf(1), sh(1)STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
