Pretzel is Mac desktop app that shows and find keyboard shortcuts based on your current app.
MacOS already has similar functionality
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!landen has used this product for one day.
IMO the best way I've seen yet to present keyboard shortcuts besides the few apps that have their own cheatsheet mechanism.Cons:
Only a couple handfuls of products are supported right now
I have a very bad short term memory *cough* (nothing to do with living in Washington state) so I find tools like this incredibly handy. And it is just that - incredibly handy.Rick Sheahan has used this product for one day.
