Keyboard Mappings
Symbolic mapping
Breadbox uses symbolic mapping of the keys. This means that the symbols you type on your computer are linked to the same symbols (or key combination that creates the symbol) on the simulated computer. Obviously, some symbols don't exist on the simulated computer. If so, the key is linked to another key, with fuzzy logic. Another obvious thing is that the simulated computer has symbols that are not on the PC keyboard. In that case, you have an option to zoom in to keyboard and click the symbol with your mouse pointer.
In short, pressing symbols like a, b, 1, 2, !, @, $, ., (, * should all give the same/similar output on simulated computer.
Some of the function and modifier key mappings are not that obvious and can be different depending on the computer model. Below you will find key mapping tables to help you locate them.
Numeric keypad (number pad, numpad)
The numeric keypad has two modes that you can change by pressing the Numlock key. By default, it operates in calculator mode and displays numbers and symbols related to the calculation. In the other mode it works as an alternative navigation keypad. Then you can use 8,4,6 and 2(or 5) as an navigation/arrow keys, in the same way you'd use the normal arrow keys to move the cursor.
Keyboard layouts
There are many different PC keyboard layouts. Basically, it means that some of the symbols are different or in different places. In order to have working symbolic mapping, a correct layout (or a close match) should be selected in Breadbox.
Currently available keyboard layouts are:
- US - American
- UK - British
- DE - German
- DK - Danish
- ES - Spanish
- FR - French
- FI - Finnish
- IT - Italian
- MX - Latin American
- NO - Norwegian
- PT - Portuguese
- SE - Swedish
