To enable dark mode for all websites we can set the chrome://flags "Auto Dark Mode for Web Content" flag name: #enable-force-dark

We can set marks with m followed by a letter or number. For example:

ma

Then to navigate to that mark we use ` followed by the letter:

`a

This is buffer specific meaning you can't navigate to marks you set in other buffers.

This also works in evil mode.

To make a field in a table blank we can use (org-table-blank-field).
