The :GBrowse command from vim-fugitive is a great way to open a file or range in the configured upstream provider (e.g. GitHub). However, it's usually a pain since it opens in the current branch, which is often not pushed.

I use scratch (unnamed) buffers in Vim a fair bit when working with text manipulation for content not saved to a file such as editing some JSON, or building some commands to run from a list of ids. Knowing how to easily create scratch buffers is a must have when using Vim.

In Vim, sometimes I want to jump to a specific column. For example, jumping to column 80 (the print width of the file), to do some reformatting. Thankfully, this is pretty easy using the | command.
