1. Avoiding the ESC key in Vim (and Readline)

    It’s probably safe to say that I should’ve changed this (ugh) habit years ago, but I just never got around to it. Thanks to Stephen, I’ve finally updated my .vimrc to exit insert mode using:

    inoremap jk <ESC>
    

    Yay!

    More importantly, if you tend to set vi editing mode in readline, you definitely want to change its bindings as well. I found this gem hidden deep in the Vim Tips Wiki.

    All you have to do is edit your .inputrc file with the following: set editing-mode vi set keymap vi

    $if mode=vi
        set keymap vi-command
        "ii": vi-insertion-mode
        set keymap vi-insert
        "jk": vi-movement-mode
    $endif
    

    As a note: Readline will pick these settings up for every readline enabled app (IPython, etc)

    Happy Vimming! :D
