Similar to how Windows and office work, display underlines (Windows) or hovering tips (Alt + Key combos) to show what the shortcut is Ex: Windows Installer - N is underlined for Next, B for Back, C for Custom, O for Complete, etc (so I can just press N to continue) Ex: Office 365 - Press Alt and the ribbon displays what letters to press for each menu item, which is great way to learn and memorize the shortcuts
