@[at]- Button doesn't work with the normal shortcut alt+L
A few days ago my MBP, MacOS 10.8.4 doesn't wrote the @ with the shortcut alt+L. I have to press ctrl+alt+L to write it.
Is there any Option to bring back the old shortcut alt+L? I have the same thing with the €-Button.
Thanks for helping me.
