elpa-expand-region 0.11.0-1 (arm64 binary) in ubuntu zesty

 Expand region increases the selected region by semantic units. Just keep
 pressing the key until it selects what you want.
 .
 Expand region works fairly well with most languages, due to the general
 nature of the basic expansions. However, most languages also will benefit
 from some specially crafted expansions. You can add your own expansions to the
 languages of your choice simply by creating a function that looks around point
 to see if it's inside or looking at the construct you want to mark, and if
 so - mark it.
