I just updated from Photoshop CC to Photoshop 2020. One of the tools I use often is "Toggle composite and grayscale mask in Quick Mask mode", which has a default keyboard shortcut of "~" Tilde in Photoshop CC. However, in Photoshop 2020, this has been re-assigned to a new function called "Toggle between painting and erasing with the same brush tip". Pressing or holding the ~ key activates the new function instead.
How do I "Toggle composite and grayscale mask in Quick Mask mode" now? I can't find/re-assign either of the aforementioned functions in keyboard shortcuts. I tried toggling both "use legacy shortcut" options in the keyboard shortcut menu, followed with a Photoshop restart, with no success.
