The following keyboard shortcuts are available by default. Mod
means Cmd on OS X and Alt on other platforms, but it
can be re-configured as another key. See the "modifier key" section for more
Note: The shortcuts are mapped against keys on a English keyboard,
so on international keyboards, the key (symbol) you have to press may
in some cases be different (but same physical key).
- Use F12 to enter the FS-UAE on-screen menu.
- Use Mod+F or Mod+Return to
toggle full-screen mode.
- Use Mod+Z or F11 to cycle through zoom modes.
- Use Mod+B to toggle extra visible border.
- Use Mod+S or Print Scrn to save a screenshot
of the current Amiga frame to the desktop (or chosen screenshots location).
- Use Mod+Q or Mod+F4 to quit.
- Use Mod+D to activate (console) debugger.
- Use Mod+G to release or acquire the input grab. You
can also use the middle mouse button, or enter the menu.
- Use Mod+K to enable full keyboard emulation. This
disables the modifier key to make it usable in emulation. In order to
disable full keyboard emulation you need to press
AltMod+K. This will usually be
F12+K. Please see the "alternative modifier keys"
- Use Mod+Up when you need to press Amiga cursor
up and joystick emulation is enabled. Similar for
Mod+Down, Mod+Left and
- Use Mod+W to toggle warp mode (no frame limit,
no audio). This does not affect the emulation accuracy, it only removes the
pauses between generating frames.
- Use Mod+R to perform a soft reset.
- Use Mod+T to perform a hard reset.
- Use Mod+P or Pause to toggle pause mode.
- Use Mod+C to activate cartridge (Action Replay, ...).
- Use Mod+, to decrease FS-UAE volume.
- Use Mod+. to increase FS-UAE volume.
- Use Mod+M to mute FS-UAE (press again to unmute).
- Use Mod+N to mute floppy sounds (press again to unmute).
- Use Prev (multimedia key) to go backward through the swap list.
- Use Next (multimedia key) to go forward through the swap list.
- Use Play (multimedia key) to insert the currently selected
swap list entry into
RTG graphics control (shortcuts are subject to change)
- Use Mod+F9 to toggle chipset/RTG display.
* Use Mod+1 to switch to chipset display.
* Use Mod+2 to switch to RTG display (if any).
- Tab – toggle chat function.
- Ctrl+F10 – Toggle performance graphs / FPS display (There are two FPS numbers shown, SYS: actual video output frame rate. EMU: emulated video frame rate).
- Alt+Tab (or Cmd+Tab) – Switch to another window / release input grab.
Note: It is possible to customize the keyboard shortcuts. See
The modifier key is the key used to trigger special keyboard shortcuts. The
default modifier key is Cmd on OS X and Alt on all other
operating systems. From now on, we will refer to the modifier key as
Note: You can specify another key with the
Since Mod is used to trigger special actions, this key is not
directly usable for Amiga emulation. This means that -- unless you have
overridden the modifier key -- you will not be able to use this key alone
to trigger the Amiga "Left Alt" key. The solution to this is to enable full
keyboard emulation when you need it by pressing Mod+K.
Note: On OS X you'll have problems with the "Left Amiga" key instead.
Alternative modifier keys
The F12 and F11 are always available as modifier keys.
This is useful when full keyboard emulation is enabled since the normal
modifier keys is then disabled. The Amiga does not have either F11 or F12, so
this does not interfere with the emulation.
Note: On many laptops the function keys can only be used while pressing
Fn. If this is the case on your keyboard, you need to hold this
key as well when you are asked to use a function key.
Function keys in OS X
On OS X, using a function key (if necessary in combination with
Fn) may trigger a desktop function such as the "Dashboard"
instead. So in order to be able to use for example F12 you may
need to add another modifier key such as Cmd into the mix so OS X
will not recognize the key combination. For example
Cmd+F12 will not trigger the "Dashboard", but will still
open the FS-UAE menu, since FS-UAE allows F12 to be used with any
Depending on your keyboard setup, you may even have to press
Fn+Cmd+F12. This is getting a bit ridiculous,
so what you can do instead is one or more of the following:
- Avoid the use of function keys where possible. You can use
Cmd-based shortcuts instead for most purposes.
- Alter OS X keyboard settings so function keys can be used without
- Alter OS X preferences and disable the desktop shortcut for the function key
you want to use, for example F12.
- Use a gamepad to open/close the FS-UAE menu.
- If you do not want to alter OS X settings, but still want to be able to
open/close the FS-UAE menu using a single key press, you can use
input mapping to assign
action_menu to a keyboard key.
You should choose a key which you do not need to use for Amiga emulation.
