I think aliasing a filter like that is an excellent idea.  It would be very
useful for the types of display filters I make.

Michael,
 
To find out what display filters are available, click on the "Expression..."
menu item on the Filter Toolbar.
 
I'm not sure what you mean by your 2nd question. The string  "nbns or nbp or
nbss or ncp or ndmp or netbios" is a valid single search string. (Note that ncps
isn't a valid protocol). You can just apply this as a display filter. If you
what you are alluding is to there a single word that encapsulates all those
protcols the answer is no. You can however save any filter string by clicking on
the "Filter:" button. 
 
Michael just gave me a thought though - how about we have a way of using the
saved filter string within subsequent filters. This way you can use the saved
filter as an abbreviation (like a #define) that could be referenced say with a
"filter:xxx" designation. For instance I have saved a filter called "tcpstart"
which is defined as "tcp.flags.syn == 1 && tcp.flags.ack == 0". What would be
great is to be able in subsequent filters type something like
"ip.addr==192.168.222.0/24 && filter:tcpstart". Any takers?
