What Neovim changes: Y and saner defaults

Y yanks to the end of the line, 007 counts in decimal, and a tour of the defaults.

?how it works

Neovim is Vim with better defaults: a lot of what people used to put in their vimrc is simply switched on. A few you'll notice straight away:

Y yanks from the cursor to the end of the line, so it matches D and C. In classic Vim it yanks the whole line like yy.
<C-a> and <C-x> treat 007 as seven. 'nrformats' is "bin,hex", so a leading zero never means octal, and the zero padding is kept: 009 plus one is 010.
'hlsearch' and 'incsearch' are on, 'autoindent' is on, the status line is always shown and the mouse works.
Q replays your last macro instead of dropping you into Ex mode, and <C-l> also clears search highlighting.

Neovim also has default mappings that only make sense with a real project open: LSP keys such as grn (rename), grr (references) and K (hover), and bracket pairs like ]d/[d (diagnostics), ]q/[q (quickfix) and ]b/[b (buffers). This editor has one buffer and no language server, so they're just good to know. The rest of this module drills the ones that work here.

Mnemonic: Y joins the capital-letter family that runs to the end of the line: D, C, Y. Want the whole line? That's yy.

Nin neovim

Y is a default mapping to y$ (:h Y-default); :unmap Y gives you Vim's version back. 'nrformats' defaults to "bin,hex" (:h 'nrformats'). The full list lives in :h vim-differences.

2 drills

Y: yank the rest of the line: Copy everything from the cursor to the end of the line onto the end of the line below, using Y.
Counting with zero-padded numbers: Make the number match the target with <C-a> or <C-x> and a count. The cursor doesn't need to be on the number.
