It does the same thing on my machine if I hit F12 in a terminal. Try looking at the keypress event in xev. If I run 'xev' hitting F12 gives me a keyboard event looking like this:
Code:
KeyPress event, serial 34, synthetic NO, window 0x5800001,
root 0x4e4, subw 0x0, time 610537995, (-159,-460), root:(712,19),
state 0x10, keycode 96 (keysym 0xffc9, F12), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
Since F12 works as a shortcut in LibreOffice Writer (start numbered list) on my machine, I believe the behaviour in the terminal is normal.
