How Can I Run a PowerShell Script from Another Active Window?

PowerShell isn't really designed for this kind of task. I recommend checking out AutoHotkey instead. It's a great tool for controlling key bindings and can help you run scripts from anywhere, not just when the PowerShell window is in focus.

If you're open to some coding, you could directly hook into the keyboard and monitor for your specific keystroke. This will likely require some C++ or C# coding. You can find more on how to do this in the official Microsoft documentation. It's not the easiest route but it would work.

You're tackling a pretty complicated issue here! Just a heads up, passing keystrokes to a background application isn't straightforward because they usually only go to the focused window. You might want to keep that in mind when considering your next steps.

It sounds like a bigger challenge than you think! Collecting key presses in the background usually needs a specific handler application that can capture those events, which isn’t trivial. Plus, PowerShell isn’t built for that kind of task. You might want to explore other solutions.
