The first obvious way is to create a shortcut (.LNK) file in the Start Menu (or on Desktop) and in the Properties dialog to assign a keyboard shortcut (let’s say Ctrl + Alt + F10).
However, this way seems to have different issues, such as the shortcut key does not work if I’m pressing it in Firefox in Full Screen Mode (F11) or when playing a Flash video (such as a Youtube video) in Full Screen Mode.
Are there any other built-in ways in Windows to define a custom global shortcut? Maybe in the registry, etc.?
I’d like to avoid using RegisterHotKey because it would require my C# program (even simple .NET programs take a lot of memory) to always run in the background waiting for the hotkey (plus it must start with Windows, etc.)
Or are there third-party programs written in native code that are very small and can be deployed with my program to help me accomplish the task of having a hotkey for my C# program?
Here is a solution from a related Stackoverflow post:
