Mojave backslash keybinding

This year, I decided not to wait a whole year before installing the latest macOS Mojave. I thus grabbed it as a beta…and now have a keybinding issue, where backslash opens a help menu instead of typing \.

To restore the old pre-Mojave behavior, just open Keyboard Settings in System Preferences and select Shortcuts. Select Application shortcuts then uncheck Show help menu, like this:

Keyboard Settings

After this, the standard backslash keybinding should work once again.
