Problems with adding new rules

People, sorry if this is an unfitting place to post this thread, but I am stressed and hopeless. It’s all because I got problems installing my tablet. I’m using instructions from
Wacom USB tablet howto - openSUSE

Now, X11 assigns the driver to the input device, but the kernel gives the Wacom a new device name every time it’s plugged in. We don’t want to edit xorg.conf and restart X every time we plug in the wacom, so, to get around this, we can create a rule that says any device with the Wacom’s Vendor ID will also be assigned the additional device name “wacom”. To do this, fire up your favorite text editor as root and add this line to /etc/udev/rules.d/10-local.rules:

(you may need to make the file, and DO NOT JUST COPY THIS LINE! Make sure to check your Vendor ID and change it appropriately)
KERNEL==“event*”, SYSFS{idVendor}==“056a”, NAME=“input/%k”, SYMLINK=“input/wacom”

Well no 10-local.rules there, and I can’t create a new one, apparently I don’t have access ! Heck, even if I could, the icon of the text document I created is completely different regardless of copying the entire file name entirely.

Can anyone help?

Of course when fiddling around wth udev rules you should be root. Apparently you are not when you cannot create the file. So start console as root and use vi or start kdesu <your-editor> or how you do those things.
