If the horizontal scale is expanded, when the marker reaches the edge of the spectrum window,
the next key press past the edge shifts the window to the next block of channels in that direction
such that the marker is now in the center of the display.
7.2.2. Next/Previous ROI <Ctrl +
6
>/<Ctrl +
7
>
The <Ctrl +
6
> and <Ctrl +
7
> move the marker to the beginning of the next higher channel
ROI, and the end of the preceding ROI, respectively, of the displayed spectrum. These functions
are duplicated by the Find Previous ROI and Find Next ROI buttons on the Toolbar.
7.2.3. Highlight Channels Left/Right <Shift +
6
>/<Shift +
7
>
The <Shift +
6
> and <Shift +
7
> keys allow you to highlight a block of channels from the cur-
rent marker position to the left or right, respectively. This is the keyboard equivalent of high-
lighting a block of channels by clicking and dragging with the mouse. You can then perform
such operations as marking the highlighted region as an ROI and calculating the centroid of the
region.
7.2.4. Next/Previous Library Entry <Alt +
6
>/<Alt +
7
>
These keys move forward or backward through the peak-identification library to the next closest
library entry. Each button press advances to the next library entry and moves the marker to the
corresponding energy. Also, instead of indexing from a previously identified peak, the marker
can be positioned anywhere in the spectrum and these keys used to locate the entries closest to
that point. If a warning beep sounds, it means that all library entries have been exhausted in that
direction, or that the spectrum is not properly calibrated for reaching further entries with the
marker. In any case, if an appropriate peak is available at the location of the marker, data on the
peak are displayed on the Marker Information Line. These functions are duplicated by the
Library indexing buttons on the Sidebar.
7.2.5. First/Last Channel <Home>/<End>
These keys move the marker to the first or last channel of the spectrum.
7.2.6. Jump 1/64 Screen Width <PageDown>/<PageUp>
<PageDown> and <PageUp> jump the marker position to the left (to lower channel numbers) or
right (to higher channel numbers), respectively, 1/64 of the window width, regardless of the
horizontal scale. The status of the ROI bit is not altered when the marker is moved with these
keys, that is, the mark/unmark state is ignored. The marker channel contents and Marker Infor-
mation Line are continuously updated as the marker jumps, so when the jump is complete, the
marker information is up-to-date for the current channel.
