69
7.2.7. Insert ROI <Insert> or Keypad<Ins>
These keys mark a selected set of spectrum channels as an ROI. To select the channels to be
marked, highlight the region by clicking and dragging the mouse from one edge of the region to
the other edge. These accelerators duplicate the function of the Mark ROI Toolbar button and
the ROI/Mark ROI command (see Section 6.5.3).
7.2.8. Unmark ROI <Delete> or Keypad<Del>
<Delete> and Keypad<Del> clear the ROI bits of all ROI channels contiguous to the channel
containing the marker. These accelerators duplicate the function of the Clear ROI button on the
Toolbar and the ROI/Unmark ROI command (see Section 6.5.4).
7.2.9. Taller/Shorter <
8
>/<
9
>
The <
8
> and <
9
> keys decrease or increase the vertical full scale of the displayed spectrum so
the peaks appear taller or shorter, respectively. The minimum is 16 counts-full-scale; the maxi-
mum is 1024 million counts. Each successive key press doubles or halves the full scale until the
maximum or minimum is reached. Whenever the maximum full-scale value is reached, the next
<
8
> key press switches to logarithmic scale. If the display is already in logarithmic scale, the
display switches to linear scale. In either case, the vertical full-scale value is always shown on
the Sidebar. Note that if the number of counts exceeds the full-scale value, the data points will
be displayed at the full-scale value unless Wrap Mode has been selected (see Section 6.6.9.2).
These keys duplicate the <F6>/<F5> keys.
7.2.10. Shift Compare Spectrum <Shift+
8
>/<Shift+
9
>
In Compare mode, the <Shift +
8
> or <Shift +
9
> keys decrease or increase the vertical separa-
tion between the two spectra. Each successive key press increases or decreases 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.
7.2.11. Wider/Narrower Keypad<+>/<
!
>
Keypad<+> decreases the horizontal scale of the Expanded Display Window so the peaks
appear wider, while Keypad<
!
> increases the horizontal scale, making the peaks look narrower.
The horizontal and vertical scale values are displayed on the Sidebar. These functions are
duplicated by <F7>/<F8>.
7.2.12. Screen Capture <PrintScreen>
The <PrintScreen> key captures the entire monitor display to the Windows Clipboard, where it
is available for use in other applications such as word processors, Windows Paint, etc.
