Oddly, this is not per-user but per mouse/usb port combination, which means if you plug the same mouse into a different port it scrolls in the opposite direction. For other mice, you can FlipFlopScrollWheel.
Oddly enough, Microsoft mice come with a Windows driver that let you reverse scroll direction via the UI. Since about the time that iPhone launched, OS X scroll direction, both mouse and keyboard, has used the metaphor of "push the document up to move it up the window" rather than the previous "push the scroll bar up to move the document down the window." Windows has stayed firmly on the scrollbar metaphor.
If you swap regularly between Mac & PC, this approach works well. I got this approach from the keyboard layout used by Parallels on the Mac, which simply duplicated common shortcuts such as Ctrl-X, Ctrl-V to the Cmd-key. The other reason I use autohotkey is that it enables a cherry-picking approach to swapping or duplicating Cmd-key/Ctrl-key shortcuts, which I find works much much better than doing a straight CmdCtrl key swap. My script is, which also has shortcut keys for arranging windows on a big screen. My preferred solution for this is an AutoHotkey script, partly because after using Autohotkey for a few weeks I realised it is utterly brilliant, an all-singing, all-dancing customise-your-Windows-in-every-way tool, with an all-but-zero footprint. ⌥⌥⌥⌥⌥⌥ ⌘ ⌥⌥⌥⌥⌥⌥ Swapping between Mac and WindowsĪ further problem for constant Mac-PC swappers is repeated Cmd and Ctrl shortcut confusion: You want to type Cmd-X for cut and suddenly the Win-X menu comes up instead.
The 2020 Windows 10 update required me to reinstall the keyboard layout - it appeared in the language settings keyboard list but not in the taskbar list of available keyboards. Some third party keyboards have one less key: the ± § key is missing and the ` ~ key takes its place. … but the Apple layout hasn't changed, so this layout works for current Apple keyboards. When I wrote it I was using one of these: You want your Apple keyboard to work for windows? Behold the Apple UK Keyboard Layout for Windows Installer.
