# Fraction shortcut not working, giving strange spacing character on german keyboard

So usually when you want to enter a fraction in Mathematica, you can do so by pressing "Ctrl+/". If you are on laptop with a german keyboard however, you will have to press "Ctrl+Shift+/" since you get a "/" by pressing Shift+7. This all used to work until recently it just gives me a strange spacing character, that when translated to FullForm, shows ".1f"

I am using Ubuntu 15.04 and it always worked till now, it works fine on other machines running Ubuntu and Debian with a german keyboard.

Any ideas? Changing the shortcuts should really be the last resort as I got really used to it and don't want to change it on every machine I'm using Mathematica on...

Cheers, Matthias

• You might have a spurious key binding. Take a look at the locations for recognized key bindings mentioned here: How can I find out where a key binding is coming from?. I'd try to get in touch with support as well. – MarcoB Aug 17 '15 at 19:42

• I have exaclty the same problem with Mathematica 10.2 on Fedora 22 (64-bit). This is not a spurious key binding problem, since I also have MMA 10.0.2, 9 and 8 installed on the same system, and there everything works as it should. Switching to US English keyboard layout makes fractions work again, so this is really something related to the German layout on Linux that was introduced in MMA 10.2. – vsht Aug 18 '15 at 12:53
• ok, I contacted support. Those guys are usually pretty quick and competent so I'm hoping this issue gets resolved. – Matthias Koenig Aug 18 '15 at 15:55

• Oh, never mind my first answer: it DOES work. What I tried was Item[KeyEvent["7", Modifiers -> {Control,Shift}], "Fraction"] which seemed to make sense. – Matthias Koenig Aug 28 '15 at 20:21
