Custom buttons of the editor
Custom buttons are HTML-editor buttons, the user can add and describe their actions himself.
Do not afraid, there's nothing complicated. The first thing you need to open the file \userdata\buttons.txt. There you will see one field that serves as an example:
noindex
As you can see, we have two parameters separated by a tab. The first - the name of the button, the second - an action that will occur when you press the button. In this case, the selected text will be framed in a tag . Place the text in the description indicates an asterisk. If it is not present, then the selected text will be replaced by the description.
To add another button, you just need to describe it with a new line.
