Do you mean that you don't want to scroll through the history to get to 
the command you want?

What I use is [Ctrl]+r  Then start typing the command.  What the shell 
will do is search back through your commands to the most recent match.  
Sometimes you need to keep typing a few extra characters to get the 
right one. 

Example:  I routinely ssh to two different computers.  One is the server 
in my local network and the command is:
$ssh pecho at 192.168.168.5
The other is to vpn and remote desktop to my office using this:
 ssh -C -p 13254 pecho at xxx.xxx.xxx.xxx -L 5901:localhost:5900

if [Ctrl]+R "ssh" gives the first one, then I keep typing until I get to 
"ssh -" and the shell finds the right one.

Try it! 
(BTW this is the bash shell which I believe is the standard in Ubuntu)
