Shortcuts in x term (alias)

Question

I've brought this up before but never really perfected it,
i've spent a bit of time on it now and its very useful and quite easy to do.
Firstly the shortcuts - 'alias' is similar to macro's in windows. Its using a letter, series of letters/numbers or a word to perform a command in the shell (X Terminal) for example to become root i just run 'r' or to run apt-get update i run 'ud'
you can customize these and add your own as you want, just don't use pre built commands like rm, mv and cp
There are 2 locations you need to save these
/home/user/.profile and /root/.bashrc (can be saved to /root/.profile also)
all the root commands need to be done as 'root' and not 'sudo gainroot' as sudo gainroot doesn't read .profile or .bashrc
you will need leafpad installed for these instructions
the first place if for anything that doesn't need root access
open xterm and run
leafpad .profile
copy/paste these commands to it and save it
alias r='root'
alias sr='sudo gainroot'
alias e='exit'
alias ls='ls -a'
alias u='cd ..'
alias h='cd /home/user/MyDocs'
alias lp='leafpad'
alias t='/usr/bin/osso-xterm ""'
then run
root
leafpad .bashrc
scroll down to the bottom of the file and copy/paste these commands to it and save it, then close xterm and when you re open it all the shortcuts will work
alias r='root'
alias sr='sudo gainroot'
alias e='exit'
alias ls='ls -a'
alias u='cd ..'
alias h='cd /home/user/MyDocs'
alias lp='leafpad'
alias t='/usr/bin/osso-xterm ""'
alias ud='apt-get update'
alias ug='apt-get upgrade -y'
alias ac='apt-get clean'
alias ar='apt-get autoremove'
alias ai='apt-get install'
alias as='apt-cache search'
alias ks='kernel-config show'
alias kl='kernel-config load'
alias kf='kernel-config limits'
more advanced users can use vi to add the commands and the source command to activate them and they can be written on one line so you don't need to write 'alias' before each one if using vi

EDIT
instead of saving the root commands to .bashrc, save them to .profile instead
the directory will look like this
# ~/.profile: executed by Bourne-compatible login shells.
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11
export PATH

leave a gap then add the alias here
you can make your own up as you wish but don't use things like 'mv' and 'rm' for obvious reasons and cpitchford said its best to keep them to 2 letters.
if you're unsure about which letters you can use then just post here and i'll tell you if it'll cause a problem
