A mnemonic is a visual or auditory aid that helps an individual remember something. In computers, mnemonics are often used to make a shortcut easy to remember. For example, many menu options are displayed with an underlined character, representing a key to be pressed to access that menu or option. The shortcut key for opening the File menu is F, which stands for "file". You can press Alt+F or Command+F to access the file menu using your keyboard. In the below illustration, you can see an example of a mnemonic.
