Windsify

If you use a Windows keyboard with a Mac, or move between both machines during the day, your muscle memory breaks in dozens of small places. The setting macOS gives you swaps Ctrl and Command globally, which fixes copy and paste and then breaks Terminal Ctrl+C, input source switching, and Alt+F4 versus Ctrl+F4. Windsify handles the keyboard and the windows in one app, with per-application context rather than a global swap. Free edition, open source under GPLv3 and free permanently: Ctrl+C, X, V and Z and the ordinary Ctrl shortcuts, Ctrl+Y redo, Home and End, Ctrl+Arrow word navigation, Alt+Tab, Alt+F4, and Insert key copy and paste. Terminals are handled properly, so Ctrl+C stays interrupt instead of becoming copy. Pro, 19.99 USD once for three Macs with no subscription: Finder behaving like Explorer with Ctrl+X to cut files and F2 to rename, system keys including Win+E, Win+L, Win+D and Print Screen, and window management with Win+Arrow tiling, drag-to-edge snapping and multi-display layouts. Every download runs Pro for 14 days and then quietly becomes the free edition rather than nagging you. No account, no telemetry, nothing phones home except license activation if you buy. It detects other keyboard remappers and window managers at launch and yields to them instead of competing for the same key events. Signed with a Developer ID certificate and notarized by Apple.
