These are the default keybindings. They can be changed using the keymapper.

Note: If you're using a Mac and are having trouble with the function keys, you may need to set your F keys to function as function keys. You can do this by going to System Preferences > Keyboard, going to the Keyboard area, and checking the "Use all F1, F2, etc" box.

Key Action
ALT-ENTER Switch to full-screen (and back).
ALT-PAUSE (ALT-F16 on OS X) Pause emulation.
CTRL-F1 Show the keymapper configuration screen,
CTRL-F4 Update cached information about mounted drives. Useful if you changed something on a mounted drive outside of DOSBox. Also cycles through disk images mounted using IMGMOUNT.
CTRL-F5 Save a screenshot (goes to capture folder).
CTRL-ALT-F5 Start/Stop recording of AVI video. NOTE: You may well have some problems with this, please see Recording Video for more information.

These default bindings are also documented in the README file accompanying the software.

Language Keys

When a keyboard layout is loaded:
