command + dot become a escape key in IntelliJ 2020 which is so Annoying

> Is there workaround on this? Or is there any way to redefine the escape? 

Unfortunately, no. 

Here is related bug request: https://youtrack.jetbrains.com/issue/IDEA-230539

Feel free to vote and follow to be notified once there are any updates. 

The bug was caused by this commit 

https://github.com/JetBrains/intellij-community/commit/45cd90111db3465287585ac2e0823ea31acbbddc#diff-a70b297a57b3616baf71a3f28b8e688bL794

By default macOS dispatch command+period as escape InputEvent, we will just skip it if escape it not a prefix of any shortcuts.  The above commit add below line  to wait for the second stroke.  

myContext.setHasSecondStroke(true)

One workaround for my case is that removing all the shortcuts with `ESCAPE` prefix, and assign a shortcut 'ESCAPE' to GotoDeclaration.

below is my diff against Emacs.xml
