Imovie Shortcut keyboard command / does not work

I use the latest Imovie version, 10.4.2, with Sequoia and lately the shortcut "command /" for trimming a clip in Timeline did not not work anymore. More of that, the shortcut that appears in the menu is "/=" with a slash on the = sign. I do not have this character on my keyboard and I do not know how to get it. I asked the Apple support and they could not help with that. I download the app from the App store and I still have the same problem. Anyone has the same problem or could help ? Thank you.
