I am looking for something like they have on Windows were you can open something and it shows the commands for special symbols. I wish the macOS had something like this, maybe it does 🤷♂️. On my iPhone I have gotten used to holding down a key for these special symbols. I know macOS has them I use them but I have to look up how to add them when needed. Since My iPhone always sits in a stand beside the Keyboard is there an app that shows these commands. I know it is "command=>shift=> "whatever". The "Whatever" is what I need.
