#### 4.4.2 MarkVert

Syntax: `MarkVert [0|1]`
Abbreviation: `MV`

is the same as `Mark`, but the mark is interpreted as vertical by the clip handling commands. This means that the region manipulated by the cut/paste commands is the rectangle having as vertices the cursor and the mark. Moreover, a capital ‘`V`’, rather than a capital ‘`M`’, will appear on the status bar. Vertical cut/paste operations are useful for handling structured program indentation.
