+# Set Left and Right Margins (DECSLRM)
+
+<VTSequence sequence={["CSI", "Pl", ";", "Pr", "s"]} />
+
+Sets the left and right margins, otherwise known as the scroll region.
+To learn more about scroll regions in general, see
+[Set Top and Bottom Margins](/vt/decstbm).
+
+Parameters `l` and `r` are integer values. If either value is zero the
+value will be reset to default values. The default value for `l` is `1`
+and the default value of `r` is the number of columns in the screen.
+
+Values `l` and `r` can be omitted. If either value is omitted, their
+default values will be used. Note that it is impossible to omit `l`
+and not omit `r`.
+
+This sequence requires [enable left and right margin (mode 69)](#TODO)
+to be set. If mode 69 is not set, this sequence does nothing and left
+and right margins will not be set.
+
+This sequence conflicts with [save cursor (`CSI s`)](#TODO). If
+mode 69 is disabled, save cursor will be invoked. If mode 69 is enabled,
+the `CSI s` save cursor sequence will be disabled, but save cursor is always
+also available as `ESC 7`.
+
+If left is larger or equal to right, this sequence does nothing. A
+scroll region must be at least two columns (`r` must be greater than `l`).
+The rest of this sequence description assumes valid values for `l` and `r`.
+
+This sequence unsets the pending wrap state and moves the cursor to
+the top-left of the screen. If [origin mode](#TODO) is set, the cursor is
+moved to the top-left of the scroll region.
+
+To reset the left and right margins, call this sequence with both values set to
+"0". This will force the default values for both `l` and `r` which is
+the full screen. Unsetting mode 69 will also reset the left and right margins.
