" Better copy & paste
" When you want to paste large blocks of code into vim, press F2 before you
" paste. At the bottom you should see ``-- INSERT (paste) --``.

set pastetoggle=<F2>
set clipboard=unnamed


" Mouse and backspace
set mouse=a  " on OSX press ALT and click
set bs=2     " make backspace behave like normal again


" Rebind <Leader> key
" I like to have it here becuase it is easier to reach than the default and
" it is next to ``m`` and ``n`` which I use for navigating between tabs.
let mapleader = ","

" suspend vim
noremap <Leader>s :sus<CR>

" Bind nohl
" Removes highlight of your last search
" ``<C>`` stands for ``CTRL`` and therefore ``<C-n>`` stands for ``CTRL+n``
noremap <C-n> :nohl<CR>

" Quicksave command
noremap <C-Z> :update<CR>
vnoremap <C-Z> <C-C>:update<CR>
inoremap <C-Z> <C-O>:update<CR>


" Quick quit command
noremap <Leader>e :quit<CR>  " Quit current window
noremap <Leader>E :qa!<CR>   " Quit all windows


" bind Ctrl+<movement> keys to move around the windows, instead of using Ctrl+w + <movement>
" Every unnecessary keystroke that can be saved is good for your health :)

" easier moving between tabs

map <Leader>m <esc>:tabnext<CR>


" map sort function to a key

" then press ``>`` several times.
