Enhancement: Make "Keyboard settings" (keyboard layout) easier accessible

[Ralf Mardorf]

PS:

In theory Ubuntu developers could change it for Ubuntu only, but you
better report your concern against upstream. Keep in mind that
portability might be important, too. A user might migrate from one Linux
distro to another, or even might migrate from Linux to FreeBSD, or vice
versa.

Disclaimer: I'm not an Ubuntu{,flavour} developer, I'm just another
user.
