Start by typing the first few characters of the command, e. g.
% ping_
then use the up arrow to browse through all commands starting
with "ping"; if "ping -c 4 hometown.jones.domain.com" was the
last ping command executed, it will show up immediately, and
you can start editing the command (Ctrl+right to word-jump,
or End Ctrl+W to erase the last word, just as you prefer).
The more "words" (or characters) you have at the beginning
of the command line, the more "precise" the search results
will be ("ping" is more "precise" than "p").
For more sophisticated searching, you could write a simple
wrapper around "history | grep" (including a grep -v to remove
the search itself from the search result); this topic has been
discussed on the list, and you can surely find working code
in the archive.
