Standard way to show a character is preforming an action?

[OrangeTeny]

Hey everyone!
I'm new here and I started making my first web tease. I'm trying to make it semi-immersive- obviously it's not...real, but I'm having characters that talk, show actions and have accompanying sounds.

Now I have the following question: At a certain point I want this character to show the player images. However, I want to do it with an action, like: Asuna shows you a tablet with images. *image on your screen*.

What's the standard way to do it?
*Asuna shows you a tablet.*
//Asuna shows you a tablet.//
||Asuna shows you a tablet.||

These are a few ideas. I was thinking of using a dedicated colour but that might be hard to follow, and I want to use bold, underline and italics for emphasis..or maybe I should do it in italics after all and leave bold and underline and colour for emphasis?

What do you all think?

Personally, I give all my characters a colour that they speak in, and then anything by the narrator is left in white, so it's distinct. I just mark it as a sentence though, no fancy punctuation like that used, I think that breaks immersion if anything.

We are writing visual novels, and novels can use descriptive sentences plainly just fine.

I looked at some of your teases, that seems like a smart way to do it, thanks! I'll experiment a bit!

I do the same as Shattered fwiw. Seems to work well.
