key <AE01> { [ 1, exclam, bar, F1 ] };
key <AE02> { [ 2, quotedbl, numbersign, F2 ] };
key <AE03> { [ 3, sterling, backslash, F3 ] };
key <AE04> { [ 4, dollar, EuroSign, F4 ] };
key <AE05> { [ 5, percent, less, F5 ] };
key <AE06> { [ 6, asciicircum, greater, F6 ] };
key <AE07> { [ 7, ampersand, bracketleft, F7 ] };
key <AE08> { [ 8, asterisk, bracketright, F8 ] };
key <AE09> { [ 9, parenleft, braceleft, F9 ] };
key <AE10> { [ 0, parenright, braceright, F10 ] };
So, FN+SHIFT + (1,2, ... ) will access F1, F2, etc.
I've tested only F5 in browser to refresh page, and works like a charm.
So to access console CTRL ALT F1 ( would have to press CTRL ALT FN SHIFT and 1 keys ). I've tested here but it didn't work.
I think you will have to change some configurations.
Unfortunately I am very busy to investigate this. Maybe this I had wroted may help.
Good luck.
