 Here's a simple & useful `.obsidian.vimrc` that I'm using:

+" Have j and k navigate visual lines rather than logical ones

 nmap k gk
+" I like using H and L for beginning/end of line
 nmap H ^
 nmap L $

 ## Supported Commands

 The commands that can be used are whatever CodeMirror supports.
 I couldn't find a formal list anywhere but you can look for `defaultExCommandMap` in [the source code](https://github.com/codemirror/CodeMirror/blob/master/keymap/vim.js), or play around with trying commands in Obsidian's Vim mode.
 
-Note that the file parsing is as simple as it gets -- it just sends each line to the CodeMirror Ex-command parser. Therefore comments or other features you may expect don't work.
+In addition to that:
+- The plugin skips blank lines and lines starting with Vimscript comments (`" ...`).
+- Special support for yanking to system clipboard can be activated by `set clipboard=unnamed` (`unnamedplus` will do the same thing).
 
-Also, commands that fail don't generate any visible error for now.
