How to make custom hotkeys work in Ubuntu 16.04?

Question

ubuntu

In Ubuntu, in System Settings - Keyboard - Shortcuts - Custom Shortcuts, you can set your own keyboard shortcuts that perform certain commands.
No matter how I twisted it, I couldn't get it to work. There is a similar question
on Askubuntu.com , but nothing written there or on other sites asking for "ubuntu custom shortcuts not working" helped. If anyone knows, thanks in advance.
