I like to create aliases to speed up and maintain my quirks, follow:

cls - is the most used, to CLEAR the screen and history I put the alias in the ~/.bashrc file

alias cls='printf "\033c"'
alias l='ls -lahr'
alias g='gedit'

Now with regard to editing files (despite having some knowledge in VIM), I have preferred to use gedit!
