Keyboard issues with right alt and polish keyboard layout


My env: Win10, Intellij 2017.3, Logitech g510s (both alt say 'alt' - no altgr), system lang - us, input method - polish programmers keyboard

In all JetBrains IDEs right alt behaves like ctrl+alt. If I want to use polish letter ż - Ralt+z IDE reads it as ctrl+alt+z and reverts changes. Supper annoying. Almost all polish accented letters are affected and so few other shortcuts that should work with ctrl+alt but work also with Ralt.

I searched a lot because its super annoying but either problems were back from 2008 and resolved or didn't match my case.
I also tried the following (true and false) but it didn't work.



Yes, still no solution though


Does it work correctly in other Java Swing applications like JEdit and NetBeans?


Just installed netbeans and no, the problem does not exist. Both alt keys are highliting menu bar (File Edit View... ) but only left alt+V opens View menu.


Try adding -Dcom.jetbrains.use.old.keyevent.processing=true in Help | Edit Custom VM Options.

By the way, where did you add option?

See if switching Runtime to Oracle Java 8 helps:


I put it in Perhaps it should start with -D as this one you provided. I only have jdk and jre 8.

It works now with and -Dcom.jetbrains.use.old.keyevent.processing=true
Are there any side effects of that?

It works with only


-D should be added if you add it in Help | Edit Custom VM Options, Help | Edit Custom Properties works without -D.


Ah, alright, I was putting it in Help | Edit Custom Properties.


to VM Options doesn't fix it.

The working solution is to add to custom properties. Thank you


I have the same problem during writing commit message in PhpStorm and WebStorm also.

I've set

but Polish letters still don't work. When I use alt +o (which means ó), I can see that Optimize imports checks or unchecks. It's weird.

My system is OSX 10.14.2 . Keyboard Polish pro. PhpStorm is 2018.3.3 and WebStorm is 2018.3.3.


Have you tried -Dcom.jetbrains.use.old.keyevent.processing=true ?


Yes, it doesn't work.

Only works ż and ź. When I type alt and o, l, n, a I can see that options during commit (Before commit section) are checking or unchecking.


Damian, what keymap do you use - is it OsX 10.5+?


I'm using IntelliJ:
IntelliJ IDEA 2018.3.2 (Ultimate Edition)
Build #IU-183.4886.37, built on December 17, 2018
macOS 10.14.2

Keymap: OsX 10.5+

There seems to be no shortcuts for those letters (ć or ź) but still doesn't work. when I press option+letter. 

Update of IntelliJ + change as suggested:
> Please, go to Help -> Edit Custom Properties
> Add the next property into the file
> com.jetbrains.use.old.keyevent.processing=true

Solved issue for me.


I use Default keymap in PHPStorm and WebStorm.

Here is quick video, when I click option and "o" , "l" or "c" . Checkboxes are checked or unchecked.

Adding com.jetbrains.use.old.keyevent.processing=true, -Dcom.jetbrains.use.old.keyevent.processing=true, do not solve my problem.



Alt triggers mnemonics, but that could be disabled. Try changing ide.mac.alt.mnemonic.without.ctrl to false in IDE Regsitry (Find Action - Registry)


Disable mnemonics in controls solved problem !

Thank you.


Exactly the same problem. 
I'm working with Intellij for some time and this appeared recently. I updated Mac to Mojave. It might happen I updated Intellij as well - I do not know but this problem is quite new. 
It's really sad and more people will notice it every day.

Still does not work for me.


helps me on windows 10


The new update has broken it again :(
