The Axes Buttons region is dedicated to display Axes buttons and the Record Key Frame button.
The Axes Buttons consists of the following components:
Active
axis buttons are displayed in red. Inactive buttons are gray. The
currently selected axis is identified with a black boarder drawn around
the button.

An
axis is selected with a single button press and made active with the
Enable button. Pressing the Ctrl key along with the Enabled button
disables all other active axes.
Once
a selected axis has been calibrated, key frames may be added to the
Grid to create a curve for motor movement. The Motor Position Slider
and Timeline Slider determine where in space and time to place the key
frame on the Grid.

Pressing
the Record Key Frame button adds a new key frame, which shows up on the
Grid as a blue dot. If other key frames are already present on the
Grid, curves are computed and drawn between adjacent key frames.
The Reset Axis button clears the calibration for the selected axis.

A
press on the Reset Axis button launches a warning message. If OK is
selected, the calibration for the currently selected axis is cleared,
and must be reset with a new Mark Begin and Mark End sequence.
Record Mark
The Record Mark button adds a plus symbol '+' to the current motor location and time position on the graph.

Markers are useful for setting target positions to be hit when shaping curves with the Bezier control handles.
