The stuff in the black is the commands you type into the terminal.
and for a shortcut the command to get flash player is
Code:
sudo apt-get update
sudo apt-get install flashplayer-mozilla
"sudo" let's you run the command as the admin, just type in your password
"apt-get" is a package tool that let's you download, install and upgrade your system software very easily
"update" is the tag that tells "apt-get" to double check it's records to see if it has the newest versions of everything. It's very important to run "apt-get update" before using apt
"install" another apt tag, guess what this one does
"flashplayer-mozilla" This is what your trying to install, you can find more packages at
