Snippets requiring no customization

Strikethrough button

This puts the button in the "Advanced" section of the toolbar. To put it in the top section of the toolbar instead, replace 'advanced' with 'main'. The button uses the old toolbar's strikethrough image; to change this, change the URL after icon:.

if ( typeof $j != 'undefined' && typeof $j.fn.wikiEditor != 'undefined' ) {
	$j( function() {
		$j( '#wpTextbox1' ).wikiEditor( 'addToToolbar', {
			'section': 'advanced',
			'group': 'format',
			'tools': {
				'strikethrough': {
					label: 'Strike',
					type: 'button',
					icon: 'http://upload.wikimedia.org/wikipedia/commons/3/30/Btn_toolbar_rayer.png',
					action: {
						type: 'encapsulate',
						options: {
							pre: "<s>",
							post: "</s>"
						}
					}
				}
			}
		} );
	} );
}

Horizontal line button

This puts the button in the "Advanced" section of the toolbar. To put it in the top section of the toolbar instead, replace 'advanced' with 'main'. The button uses the old toolbar's horizontal line image; to change this, change the URL after icon:.

	$j( function() {
		$j( '#wpTextbox1' ).wikiEditor( 'addToToolbar', {
			'section': 'advanced',
			'group': 'format',
			'tools': {
