Hello, TonyShapiro!
Thank you for reporting this issue! I wonder you may have set the "RS" for more than one command.
You can find the Keyboard Shortcuts settings in: Options > User Interface > Keyboard Shortcuts > Customize.
Export the assignment as a XML file and search Shortcuts="RS". You can find out if it's also used by other commands.
Please let me know if it doesn't work.

Thanks,
Zhengrong
