Default Keyboard Controls — MAME Documentation 0.287 documentation

# 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.

Tab

  Toggles the configuration menu.

`/~ (backtick/tilde key)

  Toggles the On-Screen Display.

  If you are running with -debug, this key sends a ‘break’ in emulation.

  When a slider control is visible, the keyboard controls are the same as in the Slider Controls menu:

  - Up - select previous parameter to modify.

  - Down - select next parameter to modify.

  - Left - decrease the value of the selected parameter.

  - Right - increase the value of the selected parameter.

  - Delete - reset parameter value to its default.

  - Alt+Left - decrease the value by the largest amount.

  - Control+Left - decrease the value by 10x.

  - Shift+Left - decrease the value by 0.1x.

  - Shift+Alt+Left - decrease the value by the smallest amount.

  - Alt+Right - increase the value by the largest amount.

  - Control+Right - increase the value by 10x.

  - Shift+Right - increase the value by 0.1x.

  - Shift+Alt+Right - increase the value by the smallest amount.

Up Arrow

  Highlight previous UI menu option.

Down Arrow

  Highlight next UI menu option.

Left Arrow

  Change current UI option setting when an arrow is present on it.

Right Arrow

  Change current UI option setting when an arrow is present on it.

  Performs a “hard reset”, which tears everything down and re-creates it from scratch. This is a more thorough and complete reset than the reset you get from hitting F3.

F4

  Shows the game palette, decoded graphics tiles/characters and any tilemaps.

  Use the Enter key to switch between the three modes (palette, graphics, and tilemaps).

  Press F4 again to turn off the viewer. The key controls in each mode vary slightly:

  - 0 - restore the default number of tiles per row (hold Shift to restrict to integer scale factors).

  - Enter - switch to tilemap viewer.

  Tilemap mode:

  - [ ] - switch between different tilemaps.

  - Up/Down/Left/Right - scroll 8 pixels at a time.

  - Shift+Up/Down/Left/Right - scroll 1 pixel at a time.

  - Control+Up/Down/Left/Right - scroll 64 pixels at a time.

  - R - rotate tilemap view 90 degrees clockwise.

  - -/+ - decrease/increase the zoom factor.

  Load a save state. You will be prompted to press a key or select from the menu to determine which save state you wish to load.

Scroll Lock/Forward Delete (Mac Desktop)/fn-Delete (Mac Laptop)

  Default mapping for the uimodekey.

  This key toggles MAME’s response to user interface keys such as the (by default) Tab key being used for menus. All emulated machines which require emulated keyboards will start with UI controls disabled by default and you can only access the internal UI by first hitting this uimodekey key. You can change the initial status of the emulated keyboard as presented upon start by using -uimodekey

Escape

  Exit emulator, return to the previous menu, or cancel the current UI option.

### System and software selection menus

## 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.
