What transition word would be appropriate to indicate a shift in time or sequence?

The transition word that would be appropriate to indicate a shift in time or sequence is "then." "Then" is commonly used to show a progression of events or actions in chronological order. When writing or speaking, if you want to indicate a change in the sequence of events or a shift to a different time, you can use "then" to help your audience understand the flow of your narrative. For example:

"I woke up early in the morning. Then, I went for a run. After that, I showered and got ready for work."

In this example, "then" is used to show the order of events, indicating a shift from waking up, to going for a run, and then getting ready for work.
