Hello. I would like to toggle the sidebar on sublimetext 2 Mac (Lion). But command + B results in a error: No Build System… How do I toggle the sidebar via keyboard shortcut?

Hold down command key (while still holding down) press k and then press b.
You can change the keybinding in Preference > key binding user (see key binding default for reference).

Thanks. Added this to my user theme: {“keys”: “super+.”], “command”: “toggle_side_bar” }] Now I have sidebar toggling goodness…
