yes, with fn keys I mean blue keys. now you can press keys like * / & numbers...

also:
Fn + left arrow is key '<'
Fn + right arrow is key '>'
Fn + up = tilde '~'
Fn + down = pipe '|'

popup menu Fn+Ctrl like in XTerm for symbol table is not possible in this low level framebuffer console output.

And for ESC in vim you can press Ctrl+C
