Due to the pandemic, many daily standup meetings were converted into video calls but it is not always possible to be available on the call all the time, sometimes we have to get away from the call for a short period of time without leaving a call and it is always hard to explain this each and every time. Is there anything standard sentence/acronym for that?
A common way in more informal contexts to signify you'll return shortly is to use the acronym BRB: Be Right Back.
Another one is AFK: Away From Keyboard. This is often used when input is required or desired.
The first acronym emphasizes the shortness of the time of the user's absence, whereas the second lets others know the user cannot interact with the digital/virtual environment.
