Vim
Auto-Rebuild on Write
Depends on Neoterm plugin:
:au BufWritePost *.m T ./bin/build prince
Customise the file pattern (*.m) and the command as desired.
Open URL under cursor
In normal mode type gx to open the URL in the default browser.
Rebuild Project on Write
Using the terminal built into Neovim you can trigger a build of a project
whenever you write a file. In the example below, whenever a Rust file is
written cargo build is run. The example makes use of
neoterm, which provides the T command to
make dealing with the Neovim terminal easier.
autocmd! bufwritepost *.rs T cargo build
Use vim as a Syntax Highlighted Pager
vim/neovim come with a script that makes vim behave as a pager (like less). It's basically a
syntax highlighted version of less. Great for inspecting the content of source files. On my Arch
box it's at /usr/share/nvim/runtime/macros/less.sh.

Virtual Replace Mode
Virtual Replace mode is similar to Replace mode, but instead of replacing actual characters in the file, you are replacing screen real estate, so that characters further on in the file never appear to move.
