Put some hidden gems as new choices on your Knoppix 7.0.5 LiveCD MainMenu.
These steps add three new menu choices at MainMenu>Universal Access:

Look at MainMenu>Universal Access
Note four current choices: daisy-player, eBook speaker, orca and xvkbd.

Go to /usr/share/applications;
note absent are desktop files for aptitude, mc and xkill.
Create three files, all are chown root:root and chmod 644, as follows.

Create a file, aptitude.desktop:
[Desktop Entry]
Name=aptitude
Icon=aptitude
Exec=aptitude
Terminal=true
Type=Application
Categories=Accessibility

Create a file, mc.desktop:
[Desktop Entry]
Name=mc
Icon=mc
Exec=mc
Terminal=true
Type=Application
Categories=Accessibility

Create a file, xkill.desktop:
[Desktop Entry]
Name=xkill
Icon=xkill
Exec=xkill
Terminal=true
Type=Application
Categories=Accessibility

Save these three files in /usr/share/applications.
As root, command update-menus.

Look again at MainMenu>Universal Access.
You should now see three new menu entries.
Each of these may be edited with a gui called-up with a right-click on properties.
These edited menu files are saved at /home/knoppix/.local/share/applications
...still chmod 644, but now chown knoppix:knoppix.
Revise the Name, Icon & Tooltip on each as you please with the gui.
