XkbSetPtrActionY \- Sets the high_YYY and low_YYY fields of act from the signed
integer value y

.BI "int " "y" "\^);"

new value to set
.SH DESCRIPTION
.LP
Actions associated with the XkbPtrAction structure move the pointer when keys
are pressed and released.
If the MouseKeys control is not enabled, KeyPress and KeyRelease events are
treated as though the action is XkbSA_NoAction.
If the MouseKeys control is enabled, a server action of type XkbSA_MovePtr
instructs the server to generate core pointer MotionNotify events rather than
the usual KeyPress event, and the corresponding KeyRelease event disables any
mouse keys timers that were created as a result of handling the XkbSA_MovePtr
action.
The
.I type
field of the XkbPtrAction structure is always XkbSA_MovePtr.
The
.I flags
field is a bitwise inclusive OR of the masks shown in Table 1.

Table 1 Pointer Action Types
_
Action Type Meaning
_
XkbSA_NoAcceleration T{
If not set, and the MouseKeysAccel control is enabled, the KeyPress initiates a
mouse keys timer for this key; every time the timer expires, the cursor moves.
T}
XkbSA_MoveAbsoluteX T{
If set, the X portion of the structure specifies the new pointer X coordinate.
Otherwise, the X portion is added to the current pointer X coordinate to
determine the new pointer X coordinate.
T}
XkbSA_MoveAbsoluteY T{
If set, the Y portion of the structure specifies the new pointer Y coordinate.
Otherwise, the Y portion is added to the current pointer Y coordinate to
determine the new pointer Y coordinate.
T}
.TE
Each of the X and Y coordinates of the XkbPtrAction structure is composed of
two signed 16-bit values, that is, the X coordinate is composed of
.I high_XXX
and
.I low_XXX,
and similarly for the Y coordinate. Xkb provides the following macros, to
convert between a signed integer and two signed 16-bit values in XkbPtrAction
structures.
