Navver is a Chrome extension designed for efficient mouseless navigation, inspired by VIM commands. By simply pressing 'f', users can activate the navigator, which highlights all links on the page. Navigation can be done by searching using either a two-character code or the link text. Pressing 'Enter' allows for focusing on inputs or clicking on links, with 'Shift+Enter' opening links in a new window. Users can scroll up and down using 'k' and 'j', and left and right using 'h' and 'l'. Additionally, the extension provides shortcuts like 'gg' to scroll to the top and 'G' to scroll to the bottom of the page.
