I notice that the installer for Ubuntu Server 12.04.1 LTS contains an option that appears to allow you to toggle between more than one keyboard layout:
English (US) - English (layout toggle on multiply/divide key)
However, there is no information about this shown in the installer, and I can't find anything useful online.
I regularly switch back and forth between the US and US Dvorak keyboard layouts, and think it would be very useful to be able to toggle between layouts. How does this work, and what is this "multiply/divide" key mentioned by the installer? When I select this option, the installation appears to proceed with the US keyboard layout.
The install completed successfully, and continues to be in standard US keyboard mode.
