You can provide both, the easy experience in combination with learning
by doing. The mechanism should be something similar to visudo, quasi
viubuntustudio-control, then add a launcher and an explanation to the
Instead of viubuntustudio-control I used pluma and nano for my examples:
[weremouse at moonstudio ~]$ cat /usr/share/applications/ubuntustudio-controls2.desktop
Exec=roxterm --maximize -T "sudo pluma /etc/security/limits.d/audio.conf" -e sudo pluma /etc/security/limits.d/audio.conf
Name=Ubuntu Studio Controls 2 - sudo pluma /etc/security/limits.d/audio.conf
[weremouse at moonstudio ~]$ cat /usr/share/applications/ubuntustudio-controls3.desktop
Exec=roxterm --maximize -T "sudo nano /etc/security/limits.d/audio.conf" -e sudo nano /etc/security/limits.d/audio.conf
Name=Ubuntu Studio Controls 3 - sudo nano /etc/security/limits.d/audio.conf
[weremouse at moonstudio ~]$ cat /etc/security/limits.d/audio.conf

As default editor I'm against vi(m), even the help of nano might be
confusing for newbies. I anyway recommend usage of nano.
[weremouse at moonstudio ~]$ printf "$EDITOR \n---\n"; grep EDITOR .bashrc
Roxterm could be replaced by xfce4-terminal, but I strongly discourage
to stay with xfce4-terminal as the default terminal.
Newbies are more likely willing to use a terminal, if it's as easy
usable and as convenient as an Internet browser.
If you resize the Roxterm window, the line breaks automatically get
You can use Ctrl++, Ctrl+- and Ctrl+0 to zoom, as you do for a web
A desktop shortcut Ctrl+Alt+T is useful, it's corresponding to the
default ROXterm shortcut and could be mentioned by the menu name.
Perhaps changing it to Ctrl+T, the common web browser default, could be
For openbox it would be
[weremouse at moonstudio ~]$ grep -B2 -A2 rox .config/openbox/rc.xml
<command>roxterm --maximize --tab</command>
Xfwm/Xfce likely provide this feature too.
I added a menu entry "Actions" providing desktop shortcuts.
