Editing Symbolics layout (section)

==Description==
Since these machines ran a custom OS based on the [http://en.wikipedia.org/wiki/Lisp_programming_language Lisp programming language], the layout has a few peculiar features:
* Since Lisp is heavy on parentheses, the keys next to 'P' produce parentheses without having to press [[Shift key|Shift]].
* The keyboard has an unusual amount of modifiers and extra Shift keys which allow to type extra characters or have more levels of key bindings.
* There are Network and Local keys to switch between a local or remote prompt.

Other special features include:
* The key next to A is captioned '''Rub out''' and behaves like an extra Backspace or Delete key.
* The other Backspace sits one row lower than on PC keyboards<!-- it is at the same place as Sun Layout, which is more usual! --> and is a small key.
