Chris' Sublime Text 2 Emacsey keybindings

gistfile1.js

[

    // Chris' "emacs refugee" Sublime Text 2 key mappings. Depends on
    // sublemacspro and Wrap Plus packages, plus a custom pdb.set_trace snippet
    // named set_trace.sublime-snippet.  It outs me as someone who uses cursor
    // keys; try not to judge.

    // "bol"/"eol" goes to a logical begin/end of line; we want it to go to true
    // line begin/end, so we use hardbol/hardeol instead for ctrl-a and ctrl-e

    // Python docstrings than either sublemacs "sbp_wrap_paragraph" or sublime's
    // "wrap_lines"
