Niall has created a quick Opensearch file to add the PHP Function search to the search bar of Firefox 2 And IE7. If anyone is interested it’s available here.
For those that don’t know, this feature has existing in KDE in multiple forms for some time. For example, pressing ALT-F2 opens the Run Command dialog and typing, for example:
php:fopen
will bring up PHP.net’s own search page. The same goes for the location bar in Konqueror.
By the way, other nice short cuts in the Run Command dialog include:
-
gg: <keywords> for a quick Google search;
-
wp: <keywords> for a quick Wikipedia search;
-
dict: <keyword> for a quick dictionary look-up;
-
man: <keyword> for a man page look-up;
-
info: <keyword> for an info page look-up;
-
rfc: <number> to be brought to the relevant RFC page;
Of course, entering a command will execute it and just entering a URL will open it in Konqueror.

Colin pointed out a useful utility called lft in response to a question on IIU. lft looks like a useful alternative traceroute application as it claims to have the ability to identify stateful inspection firewalls and other useful information.
What I found immediately attractive was the -A option which displays the AS numbers of addresses along the path and also the -N which looks up and displays the network names.
e.g.
# lft -S -A www.yahoo.com
TTL LFT trace to f1.us.www.vip.ird.yahoo.com (87.248.113.14):80/tcp
