Double click within the Text Element bounding box (the dotted line showing the element's dimensions).
The Element's bounding box will now be gold, indicating you are editing it. You'll also see the text input cursor. You can now change or add more text. Click on the default text and we'll replace it with new text for this example.
You can use the options on the text editting mini toolbar to set text as bold, italic or underline, or to left-, center- or right-align it. The Image icon allows you to add an image within the text element. There are other options available on the three-dot menu. Once you are finished with your edits, select outside of the Text Element to leave edit mode and save your changes.
You'll see the Saved icon in the lower right (beside the Commit button) will turn to Saving briefly as your changes are saved. There isn't a Save function in dominKnow One. The content changes you make are saved as you work.
