Research direction

Start in Vimium's options page by reproducing the custom mapping map <a--> previousTab, then compare it with another mapping that works and trace how Option-(hyphen) is parsed and dispatched. Done means the mapping reliably triggers the previous-tab action, with the existing behavior checked for regressions.
