Custom keyboard layouts are an option to those who want to expand the functionality of their keyboards, whether to type uncommon symbols or to define custom macros. Many applications for creating custom layouts exist, such as AutoHotKey and Microsoft's Keyboard Layout Creator, with varying capabilities and learning curves. However, they are not capable of remapping more than one keyboard simultaneously. On the other hand, the software LuaMacros, by Petr Medek, allows for using multiple keyboards in Windows, but does not offer custom layout functionality. It is instead focused on executing macros written in the Lua language. Windows does not allow more than one layout to be used at once. If more than one keyboard is connected to the computer, they all share certain states (such as CapsLock), and their layout. Additionally, a Windows program (normally) has no way of identifying which keyboard device a keystroke message came from. Typically, keystrokes can be intercepted using either a Keyboard Hook or the RawInput API, both from the Windows API. Through a Keyboard Hook, it is possible to modify or even block a message generated by a keystroke, but the program cannot extract information about which device originated that message. The RawInput API, on the other hand, does provide low-level information that includes the device's name but does not allow for manipulating the messages received this way. This article by Vít Blecha describes how to selectively block keyboard keystrokes based on which device the signal came from, showing that it should be possible for an application to treat keystrokes differently for different keyboards. That, combined with an internal model of a keyboard layout, should enable a user to effectively remap multiple keyboards to simulate using multiple layouts. This application aims at providing such a solution, to allow the user to create and use multiple keyboard layouts at once in the Windows Operating System. The user interface for this program is a Layout Editor, written in C# (with WPF), targeting the .NET framework version 4.5. You can use the editor to read and edit, as well as start and stop the execution of the main program.
