#### 4.4.8 Shift

Syntax: `Shift [<|>][n][t|s]`
Abbreviation: `SH`

shifts the text on lines between the mark and the cursor either right (‘`>`’) or left (‘`<`’) by adding or removing white space on each line. The adjustment size, specified as an unsigned integer ‘`n`’, is in units of the current tab size (‘`t`’) or spaces (‘`s`’). The defaults are ‘`>`’, ‘`1`’, and ‘`t`’. Adjustments start at the left edge of a vertical mark, or column 1 otherwise. If the mark is not currently set, only the current line is affected.

`Shift` will insert tab characters only if ‘`s`’ is not used, and both of the document’s `Tabs` and `ShiftTabs` flags are set—in which case an upper case ‘`T`’ will appear in the status bar. If either of the `Tabs` or `ShiftTabs` flags is unset (i.e there is no upper case ‘`T`’ in the status bar) `Shift` will only insert spaces.

In the case of left shifts, if any indicated line has insufficient leading white space for the requested adjustment to be made, then `Shift` reports an error and makes no changes.
