             <para>&spectacle; is a simple application for capturing desktop screenshots. It can capture images of the entire desktop, a single monitor, the currently active window, the window currently under the mouse, or a rectangular region of the screen. The images can then be printed, sent to other applications for manipulation, or quickly be saved as-is.</para>

This delay can be set in increments of 1 seconds using the spinbox buttons or the keyboard.</para>

                 <para>Enabling the <guilabel>On Click</guilabel> checkbox overrides the delay. When this checkbox is enabled, pressing the <guibutton>Take a New Screenshot</guibutton> (<keycombo action="simul">&Ctrl;<keycap>N</keycap></keycombo>) button hides the &spectacle; window and changes the mouse cursor to a crosshair. The screenshot is captured when the mouse is left-clicked, or aborted if any other mouse buttons are clicked. Note that you cannot interact with the desktop using the mouse while the cursor is a crosshair, but you can use the keyboard.</para>
