Remove undesired entries in MATE "Applications" sub-menus

[Richard Owlett <rowlett@cloud85.net>]

I'm using Debian10 with the MATE desktop.
The Debian installer defaults to installing a mess of applications I 
rarely want. They end up with entries on MATE's Applications sub-menus.

Without deleting the offending applications from the system, how can I 
delete those menu entries and replace them with links to suitable 
applications.

Web search had lousy signal to noise ratio ;<

TIA
