keyboard shortcuts for posting on phpbb-forums

One thing I am really missing, is the keyboard shortcut alt+s to post.

Is there a way to get it back, or maybe another combination?

Try it in Firefox, I'll bet it'll work. Safari/Chrome don't seem to have support for some of these keyboard shortcuts. I know in Firefox, I can Control+B and get bold here - no other Mac browser that I've tried seems to pass that command through.

no, already tried that :-(
In firefox you still have to go into config and change one setting, but still no go after that.
I usually use firefox as primary browser, so the first thing I did was fiddling with those settings.
