On Windows 10, when I type Alt+Numpad1 it enters ☺ at the cursor. While I realize that this is an old function I would very much like to turn it off. I have no conceivable use for typing ☺, and it seems wasteful to lose so many useful shortcuts to something so trivial.
Is there any way to disable single-digit Alt codes for symbols such as (Alt+Numpad1: ☺, Alt+Numpad3: ♥, Alt+Numpad7: ◘) in order to use these as keyboard shortcuts instead?
Motivation: The numpad provides a very tempting set of options for assigning shortcuts in applications that allow modification of keyboard shortcuts. For example, I am running Rstudio Server inside Google Chrome, so I have a tabbed application inside of a tabbed browser, making Alt an attractive choice for shortcuts to navigate within Rstudio Server; the large number of panels make the numpad a great choice for navigating to panels.
