Some very neat work has gone in with Conkeror development lately.
Of particular note, is the page-modes work to offer a set of built-in, default modes that allow Conkeror to interact effectively with various web applications without causing keybinding conflicts. Since Conkeror is a keyboard-drive application, this makes things very sweet as far as the browser goes; before now, one had to use C-M-q in order to send commands to the application directly, and Esc to return to “normal mode”.
Some of the existing page-modes include those which support Reddit, GMail, and Google Reader. Feel free to add your own page-modes and send patches off to the Conkeror mailing list!
