switcherit switches keyboard layout with the Caps Lock key and runs quietly from the Windows tray.

• CapsLock changes keyboard layout.
• Shift+CapsLock toggles the standard Caps Lock state (capitalization) natively.
• Alt+CapsLock enables or disables switcherit.

Windows blocks a normal unelevated process from reliably controlling elevated programs. To switch layout inside programs running with administrator privileges, switcherit must also run with administrator privileges.

switcherit does not auto-elevate. Run it normally or as administrator depending on how you want to use it. This does not apply to secure desktop screens such as the UAC approval prompt itself.

Install Odin, MSVC, and the Windows SDK. Odin on Windows requires the Visual Studio C++ toolchain and Windows SDK.

.\build.ps1

The executable is written to:

build\switcherit.exe

The default build uses the Windows subsystem, so it starts as a tray app without opening a terminal window.

For a debug build:

.\build.ps1 -Configuration debug

For stdout debug logs, build a console executable and launch it from PowerShell:

.\build.ps1 -Configuration debug -Console
.\build\switcherit.exe --debug
