5.6 The “Computer Select Window”

You can bring up a “computer select window” on the shared monitor’s screen to select a specific computer from a list of computers attached to the ServSwitch. Access the window, shown in Figure 5-11 below, by pressing and releasing the left [Ctrl] key and then hitting the [Esc] (escape) key. The arrow in the column after the computer number points to the currently selected computer.

Just as it does with the configuration menus and computer labels, the ServSwitch overlays the “computer select window” on top of your current video. Use the up- and down-arrow keys on the shared keyboard to select the desired computer; when it is highlighted, hit [Enter] to immediately switch to that computer (its label will be shown). If you have more than 16 computers in your ServSwitch system, use the [PageUp] and [PageDown] keys to access the other computers, at up to

16 computers per window. Hit [Esc] to exit the window and remove it from the screen.

Use the “Configure overlay” page to set the position and color of the window (see Section 5.4.2). The height of the window will vary depending on the current “maximum computers” (maximum ports) setting. For instance, if maximum computers is set to 6, the window will have slots for only 6 computer names.
