How to use the "/" sign in keyBindings{}?

[okyr-ux]

I'd like to have something like this:

keyBindings {
    "Cmd+/" "core.actions"
}

But it doesn't work. I guess, the issue is with the / sign. I checked the Marco syntax and grammar, and didn't find anything helpful regarding this question.

UPDATE: the shortcut actually works, but the menu item still shows the original shortcut. It got me confused.
