#### The `editable-field` Widget

Syntax:

         type ::= (editable-field [keyword argument]... [ value ])

The value, if present, is used to initialize the `:value` property. The value should be a string, which will be inserted in the field. This widget will match all string values.

The following extra properties are recognized:

`:size`
  The width of the editable field.
  By default the field will reach to the end of the line.

`:value-face`
  Face used for highlighting the editable field. Default is `widget-field-face`, see User Interface.

`:secret`
  Character used to display the value. You can set this to e.g. `?*` if the field contains a password or other secret information. By default, this is `nil`, and the value is not secret.

`:valid-regexp`
  By default the `:validate` function will match the content of the field with the value of this attribute. The default value is `""` which matches everything.

`:keymap`
  Keymap used in the editable field. The default value is `widget-field-keymap`, which allows you to use all the normal editing commands, even if the buffer's major mode suppresses some of them. Pressing <RET> invokes the function specified by `:action`.
