reply to all keybinding

[schizo]

I've done a fair bit of research through the forums but haven't come up with a way to make CTRL-R map to "reply to all" instead of just "reply". Supposedly res/builtin/platformHTMLBindings.xml does it, but when I add

<handler event="keypress" keycode="r" modifiers="control" command="cmd_replyall"/>
<handler event="keypress" keycode="r" modifiers="control,shift" command="cmd_reply"/>

to it, it's essentially ignored. Then I saw from other postings that the custom bindings have been broken for a couple of months, so I unzipped every jarfile in tbird and searched for "cmd_replyall"... with no luck.

Am I missing something obvious? I really do need this functionality-- I found myself missing a bunch of CC's already. I'd hate to have to go back to eudora.

Thanks a lot for any help!
