Version 10.2, key shortcuts for matching brackets do not work?

Question

Bug introduced in 10.2

System: Linux

Once updated to 10.2, my Alt+} and Alt+) do not return a pair of brackets but a single right one, as if Alt is not pressed. Alt+] still works.

I cleaned your question. I have the same issue, so changes to your KeyEventTranslations.tr are not the issue. Additionally, I added the standard header for bugs. — halirutan, Jul 26 '15 at 12:49
Just for the record, I'm running Windows and don't have the problem. Actually, I didn't know about that shortcut until I read this post. Thanks! — Mitchell Kaplan, Jul 26 '15 at 20:20
@Chromatic Would you mind to try this on your Linux box? http://mathematica.stackexchange.com/q/89184/187 — halirutan, Jul 27 '15 at 09:33
@halirutan Tried, not reproducible. Maybe you could try "Show expression" to find any clue? — Chromatic, Jul 27 '15 at 10:16
I'm absolutely clueless why this happens. I noticed that everything is f*cked up after I paste something in the notebook (I first noticed it while answering a question and using OP's code). I then even specifically looked at the hex-codes of the complete clipboard to make sure nothing bad and invisible is pasted into Mathematica. I reported it to support. Let's see what they can make of it. Thanks for trying. — halirutan, Jul 27 '15 at 10:45
In linux I noticed similar problem , e.g. that things like ctrl+shift+7 do not produce nice superscript anymore, but some very weird symbol. Do you also have that problem as well? — Neven Caplar, Jul 27 '15 at 14:43
On Linux with German keyboard ctrl+shift+7 should produce fractions. However, this is somehow broken in the 10.2. As a workaround I remapped fractions to ctrl+alt+7 by adding Item[KeyEvent["7", Modifiers -> {Control,Command}], "Fraction"] to KeyEventTranslations.tr — vsht, Aug 15 '15 at 16:38
@Chromatic Is this something you still experience beyond 10.2? I'm running v10.4 over Ubuntu 15.10 and both Alt+} and Alt+) work as expected. — Emilio Pisanty, May 18 '16 at 15:51
@EmilioPisanty I've been using the answer below since then. Good to know they fix this bug now. — Chromatic, May 20 '16 at 11:34

If you add this to your KeyEventTranslations.tr file it works on Linux (I only tested english keyboard layout):

 Item[KeyEvent["}", Modifiers -> {Command, Shift}],
    FrontEndExecute[{
        FrontEnd`NotebookWrite[FrontEnd`InputNotebook[], "{", After],
        FrontEnd`NotebookWrite[FrontEnd`InputNotebook[], "}", Before]
    }]
    ],

    Item[KeyEvent[")", Modifiers -> {Command, Shift}],
    FrontEndExecute[{
        FrontEnd`NotebookWrite[FrontEnd`InputNotebook[], "(", After],
        FrontEnd`NotebookWrite[FrontEnd`InputNotebook[], ")", Before]
    }]
    ],

If so desired (and if I find time) I could add this to the Shortcuts` package.

(+1) I think it would be convenient to have these in the package. – Alexey Popkov Jul 28 '15 at 08:32
@AlexeyPopkov I tried shortly yesterday to update the documentation, but something did not work with my version of Workbench and Mathematica 10.2. I wished it would be easier to write documentation ... – Rolf Mertig Jul 29 '15 at 15:42
