greping multiple lines

I just found a neat way to grep multiple lines when you only know the contents of one of those lines --

Use -B n to see n lines before the match and -A m to see m lines after the match.

ie. grep -B2 -A2

Example --

root@localhost:~# echo '       Cell 52 - Address: 00:24:6C:AB:26:D3
                   Protocol:802.11b/g/n
                   ESSID:"StevesAP"
                   Mode:Managed
                   Frequency:2.462 GHz (Channel 11)
                   Quality:100/100  Signal level:-25 dBm  Noise level:-92 dBm
                   Encryption key:on

' | grep -B2 -A2 -i steve

      Cell 52 - Address: 00:24:6C:AB:26:D3
                   Protocol:802.11b/g/n
                   ESSID:"StevesAP"
                   Mode:Managed
