at all times, depending on the spectrum displayed and whether the rubber rectangle is active.
Except for Undo Zoom In, all of these functions are on the toolbar and/or the menus (Peak
Info, Input Count Rate, and Sum are only on the Menu Bar, under
Calculate). See Section 5.11 for more information on the commands.
4.4.3. Using the “Rubber Rectangle”
The rubber rectangle is used for selecting a particular area of interest within a spectrum. It can be used in conjunction with the toolbar and right-mouse-button menu commands for many functions. To draw a rubber rectangle:
! Click and hold the left mouse button; this anchors the starting corner of the rectangle.
! Drag the mouse diagonally across the area of interest. As you drag, the mouse will be drawing a reverse-color rectangle bisected by the marker line to form a “crosshair”
(Fig. 51). This makes it easy to select the center channel in the area of interest — for instance, the center of an ROI you wish to mark or unmark, a portion of the spectrum to be summed, or a peak for which you want detailed information.
! Release the mouse button to anchor the ending corner of the rectangle.
! Once the area of interest is marked, select the applicable command from the toolbar, menus, right-mouse-button menu, Status Sidebar, or keyboard.
4.4.4. Resizing and Moving the Full Spectrum View
! Resizing — Roll the mouse pointer over the side edge, bottom edge, or corner of the window until the pointer changes to a double-sided arrow (see Fig. 50). Click and drag the edge of the window until it is the size you want, then release the mouse button.
! Moving — Roll the mouse pointer onto the top edge of the window until the pointer changes to a four-sided arrow (see Fig. 50). Click and drag the window to its new location, and release the mouse button.
4.5. Buttons and Boxes
This section describes GammaVision’s radio buttons, indexing buttons, and checkboxes. To activate a button or box, just click it.
! Radio buttons (Fig. 52) appear on many GammaVision dialogs, and allow only one of the choices to be selected.

! The ROI, Peak, and Library indexing buttons on the Status Side-bar are useful for rapidly locating ROIs or peaks, and for advancing between entries in the library. When the last item in either direction is reached, the computer beeps and GammaVision posts a
no more entries
message on the Supplementary Information Line.
! The indexing buttons are displayed in two different ways, depending on whether Gamma-
Vision is in Detector or buffer mode, as shown in Fig. 54. However, they function the same way in both modes. In buffer mode, the additional features are the ability to insert or delete an ROI with the Ins and Del buttons, respectively (located between the
ROI indexing buttons); and to display the peak information for an ROI with the Info button (located between the Peak indexing arrows).
