After upgrade from Ubuntu 16.04 LTS to 18.04 LTS (with unity) the keystrokes
Shift + Alt + Down and
Alt + Shift + Ctrl + Down stopped working (btw
Alt + Shift + (Ctrl) + [Up, Left, Right] works).
I used these keybindings in PHPStorm/Webstorm. In these programs you can search what a key binding does by simply pressing those keys and when I do, Webstorm does not display/catch these keystrokes, like if they were not pressed.
I searched in CompizConfig Settings Manager advanced search in settings value, in the Settings/Keyboard/Shortcuts and with
gsettings list-recursively | grep Down and I didn't find anything.
If I press this combo outside of Webstorm Ubuntu does nothing.
Have you any idea where this keybinding could be saved?
PS: I tried this tool (screenkey) to display pressed keys. But it didn't display
Alt + Shift + Down or
Alt + Shift + Ctrl + Down
Thank you for your help
