Default Keyboard Controls¶
Controls Foreword¶
MAME supports a vast array of different types of machines, with a significantly different array of inputs across them. This means that some keyboard keys, mouse buttons, and joystick buttons will be used for multiple functions. As a result, the control charts below are separated by machine-types to make it easier to find what you’re looking for.
All of the controls below are fully configurable in the user interface. These charts show the default configuration.
Note that the defaults shown here are arranged by US ANSI key positioning. If you are using a different layout, the keys will vary.
MAME User Interface Controls¶
The controls here cover MAME functions such as MAME’s menus, machine pause, and saving/loading save states.

Default Mahjong and Hanafuda Keys¶
Most mahjong and hanafuda games use a standard control panel layout. Some keys may not be present, depending on the kind of game. For example games without a bonus game feature may lack the Take Score, Double Up, Big and Small keys, and games without gambling features may also lack the Bet key. Some games may not use all keys that are present. For example many games do not use the Flip Flop and Last Chance keys.
Due to the large number of keys, MAME only provides default input configuration for a single set of player controls. For multi-player mahjong/hanafuda games, or mahjong/hanafuda games with multiple player positions, manual configuration is required. All the keys below are fully configurable in the user interface. This list shows the standard keyboard configuration.
