First of all, C-p and C-n are much easier... the Up and Down cursor keys.
Once you know of Ctrl-R, your use of ! automatically declines drastically, and ^ehco^echo becomes non-existent. With the ! prefix, you have to be absolutely sure that the command is what you want to run, there is no chance to see its expanded form before it is executed—this may be a risk (like when you do !rm). Ctrl-R is much safer as it allows you to see/change the command while entering it. The same aplies to ^ehco^echo — just ^R e h c, then use the arrow keys to change to e c h.
Also, ! is hardly used. Except you count how many commands you are away from your designated command -- ^R to the resuce (again, surprisingly?)

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
