Often I will help one of my students and while doing so I use commands that are not covered in class, mostly because they are either a shortcut or because I am looking for something very specific. Here is a short list of some of my favorites:
show run interface:
blog_demo#sh run int f0/0
Building configuration…
Current configuration : 93 bytes
!
interface FastEthernet0/0
ip address 10.1.1.1 255.255.255.0
duplex auto
speed auto
end
show run | section:
blog_demo#sh run | section interface

show ip interface brief:

Interface IP-Address OK? Method Status Protocol

Also while doing a show run you can use the / character to find something specific:
blog_demo#sh run

- to get a quick and dirty look at your switch interface info:
# SHOW INTERFACE STATUS
Those are great shortcuts. I remember them really first becoming necessary when I started configuring Call Manager Express in IOS. Now it seems like there are so many features and configs are so long I am constantly using them. I wish the parser supported full regex and you could run debug output through a regex parser.
On a side note “/” works in Firefox as well.
