Note: Manual Incomplete
* nEXT Browser
Next Browser is the ultimate nEXT generation browsing experience
designed for power users. 100% of the functions and classes are
exposed to the end-user allowing for infinite customization.

* Basics
** History
History is represented as a tree that you can traverse. More complex
than the "forwards-backwards" abstraction found in other browsers,
the tree makes sure you never lose track of where you've been.
In the example below, the User performs the following actions:
1. Starts page ~Athens~
2. Visits page ~Ancient Greek~
3. Returns to page ~Athens~
4. Visits page ~Classical Athens~
5. Returns to page ~Athens~
6. Executes ~forwards~ keybind in history
It is at this point that a normal browser would NOT be able to
navigate you forwards to your visit of ~Ancient Greek~. Instead of
erasing your history, nEXT offers smart navigation and prompts the
user. Do you wish to go forwards to ~Ancient Greek~ or to
~Classical Athens~?
The standard keybindings for forward-backward navigation are:
1. ~C-f~: Navigate Forward
2. ~C-b~: Navigate Backward
3. ~S-f~: Navigate Forward Tree
4. ~S-b~: Navigate Backward
By using navigate forward tree you will be prompted for which branch
you'd like to visit as in the example above. The simple navigate
forward command will simply visit the first child of the current node
in the tree.
** Tabs (Buffers)
Tabs are represented by a concept known as "buffers". Buffers are
known in other GUIs as Views. Unlike in other GUI systems, the model
for a view cannot dynamically change. This is true within nEXT. Given
a buffer composed of a web-view and a document-mode model, one can
dynamically set the model to any other mode. This enables run-time
specialization and modification of widget behavior.
The standard keybindigns for tab management (within document-mode)
are:
1. ~C-x b~: Switch Tab
2. ~C-x k~: Kill Tab
3. ~S-l~: New document-mode tab
4. ~C-l~: Change URL of current document
* Customization
All customization begins by creating a =~/.next.d/init.lisp= file.
Within your init file you can write your own keybindings and
customizations.
The first line of an init file should contain the following package
declaration in order to modify nEXT specific variables and functions:
#+NAME: package
#+BEGIN_SRC lisp
(in-package :next)
#+END_SRC
Following the package declaration, you can write or override any
functions and variables.
** Keybinding
Keys are defined with the following syntax:
#+NAME: define key
#+BEGIN_SRC lisp
(define-key global-map (kbd "C-x o") #'function-example)
#+END_SRC
in the previous example, the sequence of keys: ~control+x~, lift hands
off control key, ~o~ would invoke the "function-example". Additionally
important to note is that the key sequence ~control+x~ is now
registered as a special type keybinding, a prefix. A prefix key can,
but should not be mapped. If a subsequent mapping was to bind
~control+x~, it would be unclear to nEXT what keybinding invocation
the user is trying to type.
The following keys exist as special keys:
1. ~C~: Control
2. ~S~: Super (Windows key, Command Key)
3. ~M~: Meta (Alt key, Option Key)
*** Swapping the Modifier Keys
nEXT is built with QT, and on Mac OS, QT will automatically modify
what control, meta and caps lock as keycodes sent to the key-capturing
system. In order to maintain consistency with other programs that you
are familiar with, you may want to switch to the default emacs style
keybindings; to do so; simply copy the snippet below into your
init.lisp file.
#+NAME: Emacs Style Modifier Keys
#+BEGIN_SRC lisp
(let ((original_control *control-key*)
(original_meta *meta-key*)
(original_alt *alt-key*))
(setf *control-key* original_meta)
(setf *meta-key* original_alt)
(setf *super-key* original_control))
#+END_SRC
