Note that if the number of counts exceeds the full-scale value, the data points will be displayed at the full-scale value.
These keys duplicate the function of the <F6>/<F5> keys.

In rubber-rectangle mode (see Section 4.4.3), the <Shift + Arrow> keys move the rubber rectangle one channel or one pixel at a time.
9.2.11. Compare Vertical Separation <Shift +
8
>/<Shift +
9
>
In Compare mode, the <Shift +
8
> or <Shift +
9
> keys decrease or increase the vertical separation between the two spectra. Each successive key press will increase or decrease the separation by moving the spectrum read from disk. The spectrum from disk can be moved below the first spectrum if it has fewer counts.
9.2.12. Zoom In/Zoom Out Keypad<+>/<->
Keypad<+> increases the scale of both axes in the Expanded Spectrum View so the peaks appear larger, while Keypad<-> does the opposite, making the peaks look smaller. The scale value for both axes is always shown on the toolbar.
These functions are duplicated by the Zoom In/Zoom Out buttons on the toolbar and Zoom In and Zoom Out under the Display menu. See Section 4.2 for a more detailed discussion.
9.2.13. Fine Gain <Alt + +>/<Alt + ->
These accelerators step the internal amplifier up or down by one increment of fine gain on the selected Detector, if it has a software-controlled amplifier. The new fine gain setting is shown on the Supplemental Information Line at the bottom of the screen. If the gain stabilizer is active, the display of the histogram data might not change.
The fine gain can also be set with Acquire/MCB Properties... (Section 5.2.11),
<Shift + Alt + +>/<Shift + Alt + -> on the keyboard, and Keypad<Alt + +>/<Alt + ->.
9.2.14. Fine Gain (Large Move) <Shift + Alt + +>/<Shift + Alt + ->
<Shift+Alt+ +> and <Shift+Alt+ -> step the internal amplifier of the selected Detector (if it has a software-controlled amplifier) up or down by a large increment of fine gain. If the gain stabilizer is active, the display of the histogram data might not change.
