Pretzel is Mac desktop app that shows and find keyboard shortcuts based on your current app.
It should be noted that you can already do this with MacOS. Almost all commands with their respective keyboard shortcuts are listed in the menu bar for each app, and can be searched through using the Help tab (Command + Shift + /).

That said, nothing exists on Windows that can do this yet, so I'm really eager to try this product out there!
MacOS already has similar functionality
