-===== Use of different fonts in clock panel applet ​===== +===== Customize the font in clock panel plugin ​=====

 The margins are also useful if you have only one Xfce panel: the margin area leaves a clear space to pull up application or workspace menus. By default, right click on the desktop (the margin) to show the Xfce menu, or middle (left+right) click to show the workspace menu. The margins are also useful if you have only one Xfce panel: the margin area leaves a clear space to pull up application or workspace menus. By default, right click on the desktop (the margin) to show the Xfce menu, or middle (left+right) click to show the workspace menu.
 +
 +The size of the margins is in pixels, so, with a reasonably modern monitor, at a resolution of, say 1680 x 1050, a setting of '​10'​ will give a margin of about 1/8 of an inch. Note that nothing will change on any open window until you minimize and re-maximize it again. Also note that these margins only apply to maximized windows -- you can manually resize any window right to the edge of the screen if you want to.
