The expand keyboard shortcut^1 works differently in different file types. Here's how it works in typescript files:

The selection logic is much simpler for twee files:

Although I'm not exactly sure how I would prefer this to work, I do think there's room for improvement. For example:

• If the cursor is within a macro container, it would be helpful for it to expand to the whole body of the macro container

  • then the macro tags
  • then repeat until there are no more macros around the selection
  • then select the entire passage excluding the passage line
  • then select the entire passage, including the passage line
  • then the entire file

• Since twee files contain a lot of prose, expanding selections from words

  • to surrounding quotes
  • to the quotes themselves
  • to the sentence (?)
  • to the paragraph, would probably be helpful.

Here are some helpful resources to implement this functionality ( @cyrusfirheir found these, not me ):
