    public abstract class JEditActionSet<E extends JEditAbstractEditAction>

extends java.lang.Object
implements InputHandlerProvider

A set of actions, either loaded from an XML file, or constructed at runtime by a plugin.

### Action sets loaded from XML files

Action sets are read from these files inside the plugin JAR:

- `actions.xml` - actions made available for use in jEdit views, including the view's Plugins menu, the tool bar, etc.
- `browser.actions.xml` - actions for the file system browser's Plugins menu.

An action definition file has the following form:

    <?xml version="1.0"?>
    <!DOCTYPE ACTIONS SYSTEM "actions.dtd">
    <ACTIONS>
        <ACTION NAME="some-action">
            <CODE>
                // BeanShell code evaluated when the action is invoked
            </CODE>
        </ACTION>
        <ACTION NAME="some-toggle-action">
            <CODE>
                // BeanShell code evaluated when the action is invoked
            </CODE>
            <IS_SELECTED>
                // BeanShell code that should evaluate to true or false
            </IS_SELECTED>
        </ACTION>
    </ACTIONS>

The following elements are valid:

- `ACTIONS` is the top-level element and refers to the set of actions used by the plugin.
- An `ACTION` contains the data for a particular action. It has three attributes: a required `NAME`; an optional `NO_REPEAT`, which is a flag indicating whether the action should not be repeated with the C+ENTER command; and an optional `NO_RECORD` which is a a flag indicating whether the action should be recorded if it is invoked while the user is recording a macro. The two flag attributes can have two possible values, "TRUE" or "FALSE". In both cases, "FALSE" is the default if the attribute is not specified.
- An `ACTION` can have two child elements within it: a required `CODE` element which specifies the BeanShell code that will be executed when the action is invoked, and an optional `IS_SELECTED` element, used for checkbox menu items. The `IS_SELECTED` element contains BeanShell code that returns a boolean flag that will determine the state of the checkbox.

Each action must have a property `name.label` containing the action's menu item label.

### View actions

Actions defined in `actions.xml` can be added to the view's Plugins menu; see `EditPlugin`. The action code may use any standard predefined BeanShell variable; see `BeanShell`.

### File system browser actions

Actions defined in `actions.xml` can be added to the file system browser's Plugins menu; see `EditPlugin`. The action code may use any standard predefined BeanShell variable, in addition to a variable `browser` which contains a reference to the current `VFSBrowser` instance.

File system browser actions should not define `<IS_SELECTED>` blocks.

### Custom action sets

Call `jEdit.addActionSet(ActionSet)` to add a custom action set to jEdit's action context. You must also call `initKeyBindings()` for new action sets. Don't forget to call `jEdit.removeActionSet(ActionSet)` before your plugin is unloaded, too.

Since:
  jEdit 4.3pre13
