Code Folding

The Ace Code Editor allows code folding, or hide and showing code snippets while editing. You can do this by toggling the arrowhead on the right side of the line number.

To fold/hide code sections, click the arrowhead.


To show code sections, click the arrowhead again or the double-sided arrow between the HTML tags.


Highlight Similar Text

Highlighting a word within a HTML or CML tag will highlight all matching words in the selected editor box.


Live Syntax Checker

As you type in the CML box, the live syntax checker will appear and provide information regarding incorrect syntax.
