If I run Ctrl-Tab I get the list to show open files.
If I keep on pressing Tab (while keeping Ctrl pressed), it works properly:: the list moves through open files.
I have the left-Ctrl key mapped to the CapsLock key.
I have a Windows machine, and a Linux (Xubuntu 18) machine.
Both machines have the left-Ctrl-->CapsLock mapping.
On the Windows machine, the IntelliJ list of open files opens properly, and cycles properly.
Yet on the linux machine, the list opens, yet it doesn't "open the selected file" when releasing Ctrl (physically, releasing CapsLock).
Any idea what I could check/try?
I found this similar issue from 2012. Similar, yet not the same.
