The following function and hot keys (except CTRL V) can be used in any of the Emma 02 windows in some cases the function is depending on the emulated computer.
To change the defined keys below use menu item below:
In the Function and Hot Key Mapping window that opens any of the PC keys (highlighted in blue) can be changed and the 'Exit key' and 'Paste' (highlighted in yellow) features can be enabled or disabled:
To change a key first select the button to be changed (one of the buttons in the highlighted in blue), after this 'Press Key' is shown on the button, now press the PC key it should be mapped to. Any PC key that is mapped twice will be shown in a red colour. Any key used by one of the emulators is shown in orange (orange ESC key above).
Avoid double mapping (highlighted in red) as the emulator will not be able to handle this. Re-using emulator keys (highlighted in orange) will work but it will disable proper working of the same key in some of the emulators. Using SHIFT will in most cases still work in the emulators, i.e. when enabling ESC as exit key, SHIFT ESC will still work on a COMX as the COMX ESC key.
The 'Paste' key will always be defined as a 'Control' key on Windows and Linux and a 'Command' key (⌘) on OSX. Default key for the paste feature is 'V'.
To restore default Emma 02 hot key mapping press the 'Default' button (highlighted in orange) and always press 'Save' to save the changed values.
