I use Parallels to connect to an IBM mainframe computer and use a 3270 emulator. Is there a way in Parallels to use function keys 13-24? F13 - F24?
Go to Parallels Desktop -> Preferences -> Keyboard. There you can define what keys on the Mac go to which keys on the PC. The F keys go up to F19. If you can't get F20-F24 then you could try modifying the keyboard profile files manually. They are xml files with .kbd file name extensions in ~/Library/Preferences/Parallels. Parallels key codes are defined in: "/Library/Parallels/Parallels Service.app/Contents/Frameworks/ParallelsVirtualizationSDK.framework/Versions/6/Headers/PrlKeys.h" For example, F19 is 158 so you would see it in the .kbd file as <CustomKey>158</CustomKey>
