Special Keys

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.

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).

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