I've found some custom keymaps in my PHPStorm but I cannot figure out what is their purpose and I'm pretty sure that I'm not assign them. They are:
Switching Apply (alt+shift+enter)
Switching Down (alt+shift+down)
Switching Left (alt+shift+left)
Switching Right (alt+shift+right)
Switching Up (alt+shift+up)
Does anybody know how to use these shortcuts?
