I work with many archival files and folders, so the one function I ever use on the F keys row is F2, for 'rename'. I have just bought this Pebble keyboard, and F2 is the ONLY F key that Logitech has removed its function - and also provided no shortcut replacement for. What were you thinking? F2 rename function is a necessary standard on all keyboards, yet you've removed it altogether. I don't understand. Would you please offer a firmware update or something, - as well as the reason you removed such a necessary functionality would be great too. Thanks.
