Something else helpful: by default the left convenience key is bound to the ESC button. That means emacs and irssi fans can bind “Meta” to the ESC key (this is done by default in irssi), and use the left convenience button to access many common app shortcuts.

Within the next couple of weeks, complete customization of keybindings will be released, allowing you to set up your own preferred shortcuts and key combinations to use with BBSSH.
