I think ?-> is out just on the basis that it is a chord-key-chord sequence on I think a lot of keyboard layouts. I would prefer that if we have to have a double chord sequence that they are together. By chord i mean any "key" that requires a shift to access. For me ?-> is "shift slash, dash, shift dot", which is an annoying key-sequence to want to do very often. -?> is at least, "dash, shift-and-hold, slash dot" or "dash shift-slash, shift-dot". So far ->> and ~> seem the nicest for my keyboard: "dash, shift-and-hold slash, slash" or "shift-hashmark, shift-dot". cheers, Yves -- perl -Mre=debug -e "/just|another|perl|hacker/"Thread Previous | Thread Next
