Specifies a variable whose value is changed when you press the left
a
or right cursor key, or tap the left or right graph controller arrow.
These items specify the upper limit (End) and lower limit (Start) of
the range of change of the Dynamic ]' value.
Use this setting to specify the increment of change in the Dynamic
]' value when you press the left or right cursor key, or tap the left
or right graph controller arrow.
Specifies another variable whose value is changed when you press
b
the up or down cursor key, or tap the up or down graph controller
arrow.
These items specify the upper limit (End) and lower limit (Start) of
the range of change of the Dynamic `$ value.
Use this setting to specify the increment of change in the Dynamic
`$ value when you press the up or down cursor key, or tap the up
or down graph controller arrow.
