P: Shortcut key for Object Masking tool

I would like to request a shortcut key for the Object masking tool.

Long-time user here; I've recently found that the Object masking tool is wildly useful. Not only for selecting objects but also to mask tedious details. It's improved considerable over the years and is now intelligent and accurate!

I often use it instead of the brush tool and having a shortcut key would really expedite my workflow!

Thank you for your consideration.
