Standard shortcuts cannot be substituted
InDesign CC 14.0.1 x64 - It appears that as-standard shortcuts cannot be substituted, even though they show as if they have been. Specifically the 'W' shortcut. I want to substitute Ctrl+Alt+W in a new custom list based on the default list. This avoids any possibility of entering W in text. Even though I substitute the new command and remove the standard command, the new command does not work but the old one still does. I previously was able to do this with my previous version software.
