1.84.4 Instance variables

key_binding <- argument: [int]

Current setting of the (integer) argument. The following functions set this argument:

digit_argument

If \e0 .. \e9 and \e- are bound to the function digit_argument the universal argument may be composed by typing its value with the META-key held down.

universal_argument

A value may be composed by typing the key bound to the function universal_argument, followed by the digits to construct its value.

The predefined key_binding name argument binds \e0 .. \e9 and \e- to digit_argument and \C-u to universal_argument. Using this table, the following sequences are examples for entering a universal_argument:

Sequence	Value
\e1\e4	14
\C-u56	56

key_binding <- bindings: sheet

Sheet mapping key-names to functions. The key-name is a symbolic representation of the key-sequence mapped. These names are described with the method key_binding->function. The function is either a name, in which case the key-binding will invoke the named method on the event-receiver, or a code object.

key_binding->function

key_binding <-> default_function: name|code*

Name or code object which is used when neither the key_binding<-bindings nor one of the key_binding<-defaults key_bindings define a binding for the typed key.

A common way to use this facility is to declare key_binding<->default_function to alert. Any unknown keys will then be mapped onto the method graphical->alert.

key_binding <- name: name*

Name of this binding table. Any named binding-table is stored in the global object @key_bindings for reuse.

key_binding <- prefix: name

Currently parsed prefix for multi-key functions. Its initial value is the empty name (” ). If a typed key is bound to the function prefix this variable is set to this key.

The predefined table emacs_special binds \e, \C-c and \C-x to the function prefix.

key_binding <- saved_column: int*

This variable is used to store the current column for multiple next_line and previous_line functions. Its value is managed by key_binding->event.

key_binding-status: {universal_argument,quoted_insert}*

Internal flag used to parse universal arguments.
