Vim command for markdown headline
This is a sequence that I’ve been using quite a lot since I started to learn Vim.
I write a lot of markdown and for H1 and H2 headings I often use the underlining style of setting === or --- under the title instead of prefixing # or ##.

Heading 1
=========
instead of `#`
Heading 2
---------
instead of `##`
To make it visually more pleasing I like to have the underlining be as long as the title itself.
The below sequence makes this really easy.
1

3
yyp // duplicate line
V // select line
r= // replace every character in the line with `=`
