VIM: Hard Mode
Hard Mode is a plugin which disables the arrow keys, the hjkl keys, the page up/down keys, and a handful of other keys which allow one to rely on character-wise navigation. The philosophy behind Hard Mode is that you'll never master Vim's advanced motion and search functionality if you can fall back on the anti-pattern of fumbling around your code with the arrow keys.
MAPPINGS
To enable it:
:call HardMode()
To disable it:
:call EasyMode()
To have it always enabled, add this to your vimrc:
let g:hardmode = 1
Toggling it is done with <Leader>h by default, but you can override it
by adding a line like this to your vimrc:
nnoremap <Leader>H <Esc>:call ToggleHardMode()<CR>
Presuming your leader is still the \ key, you can toggle Hard Mode by
pressing \h while in Normal-mode.
Installation
If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:
cd ~/.vim/bundle
git clone git://github.com/wikitopian/hardmode.git
Once help tags have been generated, you can view the manual with
:help hardmode.
