How does it actually work? Is it associated with the first letter?
Hi @TakWolf, generally it should be associated with the first letter, and every button in the same dialog that has the mnemonic should have a different one so there are no conflicts between buttons (so you can press Alt+O to activate the OK button, or Alt+C to activate the Cancel button, etc.).
