HTML Extended Editing Functions for tinyMCEIssue It was asked about a few extended functions for HTML field. Cleanup Messy CodeSpell CheckerPreviewPaste from word ReleaseRome and onCauseThis is our documentation that goes over what is supported and not supported. ResolutionBelow is the latest document for extended functions. If you note, Spell Checker is only available for HTML area, not tinyMC link For paste from word. Note that "paste from word" is not in this list. For this, can you please review this community post below: link Preview works when in glide.ui.html.editor.v4.toolbar.valid.buttons property. And for "Cleanup Messy Code" PRB1557463 was cr3eated and closed working as expected as the "cleanup" button is not available in tinyMCE v4. It was a v3 feature (and seen in the v3-specific system properties).
