HOWTO_SETUP_UASM.txt

You'll need to integrate UASM into Visual Studio 2022.
Download UASM x64 (http://www.terraspace.co.uk/uasm.html#p2) and open UasmTargets.zip, copy it's contents to C:\Program Files\Microsoft Visual Studio\2022\Professional\MSBuild\Microsoft\VC\v170\BuildCustomizations (default path).
Rename uasm64.exe to uasm.exe and copy it to KeyboardShortcutsFix\KeyboardShortcutsFix (the folder containing the source code).
Done. My project will now open and compile.
