How to express action (in plays, and online)

Question

So in most languages we can either put text in italics or between asterisks to indicate what the speaker is doing. For instance:

Looking up It will be raining soon

Or on the Internet:

*chewing your tacos* can i borrow food from you?

Is there any equivalent forms in Japanese?

Answer 1

You can just enclose the action with parentheses. For example, "Looking up It will be raining soon" will be （見上げながら）雨が降りそうだ。Note that full-width parentheses（）looks nicer than normal parentheses () in Japanese sentence.
