9. KEYBOARD FUNCTIONS
This chapter describes the GammaVision accelerator keys. The keys described in this section are grouped primarily according to location on the keyboard and secondarily by related function.
9.1. Introduction
Table 17 provides a quick reference to all of the GammaVision keyboard and keypad functions.
These accelerators are also illustrated in Fig. 300, and discussed in more detail in the remainder of the chapter.
The accelerators are available only in the GammaVision window. The title bar must be highlighted with the active title bar color (as set up in Windows Control Panel). In addition, the active cursor — or input focus — must be in one of the spectrum windows. Similar to other
Windows applications, the focus can be switched between GammaVision and other applications by clicking on the Windows Taskbar, pressing <Alt + Tab>, or, if the inactive window is visible, pointing with the mouse at some spot in the inactive window and clicking.
The multi-key functions, such as <Alt + 1> or <Shift +
6
>, are executed by holding down the first key (e.g., <Alt>, <Shift>, or <Ctrl>) while pressing the key that follows the “+” sign in the brackets, then releasing both keys simultaneously. Functions that use the keypad keys begin with the word Keypad, e.g., Keypad<5>.
As usual for any Windows application, the menus are accessed by clicking on them with the mouse, or by using the Alt key plus the key that matches the underlined letter in the menu item name. For example, the multi-key combination to activate the File menu is <Alt + F>.
Note that the GammaVision accelerator keys do not interfere with Windows menu operations or task switching. For example, when a menu is active (i.e., pulled down), the <
7
>/<
6
> and
<
8
>/<
9
> keys revert to their normal Windows functions of moving across the menu bar and scrolling up/down within a menu, respectively. As soon as the menu is closed, they behave as
GammaVision accelerators again.
9.2. Marker and Display Function Keys
9.2.1. Next Channel <
6
>/<
7
>
When not in rubber-rectangle mode, the right and left arrow keys move the marker by one displayed pixel in the corresponding direction. This might represent a jump of more than one spectral data memory channel, especially if the horizontal scale in channels is larger than the width in pixels of the window (see the discussion in Section 4.2).
