You can use only Latin letters, digits, F-keys, punctuation signs and shortcut keys, neither Cyrillic nor other national symbols could be used. In case F-key is used please enter f1 for F1 key, f2 for F2 key etc. If you need keys with modifiers, just enter first modifiers letters and then the key. I. e. use c1 for Ctrl-1, cs2 for Ctrl-Sift-2, casf3 for Ctrl-Alt-Shift-F3 and so on.
