[...]Please press the three keys CTL ALT and t together to open a terminal window.[...]
The
CTL+ALT+T accelerator does nothing on my machine, for years!

So, I thought a different path would be of some use:
Main menu ---> System ---> XFCETerminalUsually, (the default configuration) it has to be a button on the left side of the Taskbar with the Terminal icon on it.
I never use those, because I have three buttons placed in three different places. Just in case...

I avoid as much as I can the CLI, but when it comes to choose between "
Ugly" and "
Fast", I'd rather choose "
Fast"...

Another approach, is to use the File Manager and go to
/bin than double-click on
xfce4-terminal or simply select it and press
Enter.
Best regards!
