Note that virtual keys are not always at the same place. For example, Q is next to the Tab key on US keyboard but next to the Caps Lock on French keyboard. You can click on each keyboard layout to find out how it defines the mapping.
Please note current limitations of the algorithm:
- First found sequence is accepted, i.e. there might be better or more common ways of typing something on given keyboard.
- It is greedy, i.e. if you have keys K, KA and AH, typing KAH will be deemed impossible as the KA key will be used and there is no H key.
- It does not consider edits, i.e. it will claim A is impossible to type in the previous example, even though you could use AH and backspace.
- It does not combine dead keys with ligatures, i.e. if you had ˇ + C = Č rule and there were only ˇ and CE keys, typing ČE would be deemed impossible.
- It does not consider normalization equivalence, i.e. composite Ó cannot by typed using O and combining acute, either as a ligature or as separate keys.
