How to add the Alt+Backspace macOS typing functionality to Windows
Please use Ctrl + Backspace on Windows to delete an entire word.
You can remap the hot key using AutoHotkey.
The following script will do it. Set it up to run on Windows start up or when you log in.
!BS::
Send ^{Backspace}
Note: On my PC, Alt-Backspace seems to be Undo, same as Ctrl-Z. AutoHotkey will replace the existing functionality while the script is running.
