#### 4.4.3 Copy ¶

Syntax: `Copy [n]`
Abbreviation: `C`

copies the contents of the characters lying between the cursor and the mark into the clip specified by the optional numeric argument, the default clip being the current clip, which can be set with the `ClipNumber` command; see ClipNumber. If the current mark was vertical, the rectangle of characters defined by the cursor and the mark is copied instead.
