" Usability options
"
" These are options that users frequently set in their .vimrc. Some of them
" change Vim's behaviour in ways which deviate from the true Vi way, but
" which are considered to add usability. Which, if any, of these options to
" use is very much a personal preference, but they are harmless.

" Use case insensitive search, except when using capital letters
set ignorecase
set smartcase

" Replace all matches on the line, not just the first,
"  by default, without requiring …/g
set gdefault

" Incremental search
set incsearch

" Set the search scan to wrap around the file
set wrapscan

" Always display the status line, even if only one window is displayed
set laststatus=2

" Use <F11> to toggle between 'paste' and 'nopaste'
set pastetoggle=<F11>
