A couple of queries...

[Philo-U]

Hi - the link to "available actions (listed at https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand)"... this linked to page says the execCommand() method is deprecated.... is likely to cause issues down the line with this editor?

[edit] oops, just seen the thread on this in the "General" discussion... ok, never mind this then.

But, that aside,... JS isn't really my strong point (still trying t work out what is! :) ) and am struggling abit to figure out how to add a custom toolbar item that will wrap the selected text as per:
<span class="myClass">selected text</span>

tia for any clues!
