We can create short text passages called text-only pop-up messages that appear when a user clicks a linked term.
Creating text-only pop-ups
Select the text in the Design Editor and from the Insert tab, click on the Text Popup icon. Type the pop-up text directly into the window.
Edit text-only pop-ups
To edit text-only pop-ups, Right-click on the text, which has been assigned the text-only pop-up. Then we should select the Text Popup Properties…
The next step is to type or edit the text in the Popup Text box. You can also change the size, background color, fonts and margins. Future text-only pop-ups will carry forward these options.
