You could add an ability to the monk's character sheet (in the Attributes & Abilities tab) that contains the description of the Stunned condition. Then you could add an Ability Command Button to the description of their attack that refers to that ability. For example, if the ability was named "stunned-condition" and the character was named "Bob", then the ability command button to display the description in the text chat would be: [Stunned Condition](~Bob|stunned-condition). Mind you, that "|" is not a capital i, but a straight bar or "pipe" character. Edit: You could also create a handout called "Stunned Condition" with the stunned condition text. Then, from another, different handout you can link to it by putting it inside brackets, like so: [Stunned Condition]. If you save this different handout like this, there will be a link to your "Stunned Condition" handout. If you right click that link and copy the URL of that location/address, then you can use that in the description of the character's attack like so: [Stunned Condition](<paste the URL here>). If your player then uses that attack and the description shows up, then anyone can click on the text "Stunned Condition" to pop open the handout you made.
