I could probably shave a nice hunk of time off of my labs if I could just reduce the number of times that I’ve had to retype a command because I was:
1) In configuration mode and forgot to type “do” before my command.
2) I was in enable mode and accidentally typed “do” before my command.
I also choke on typing “conf t” quite a bit. This is generally when I’m trying to type too quickly. For whatever reason my fingers seem to want to type a space after the ‘n’ (“con ft”).
Oh well, as the title of this post suggests, it’s not retyping a couple of commands that it going to sink me on the lab exam. :-)
