"Usage: wmctrl [OPTION]...\n" \
"Actions:\n" \
" -m Show information about the window manager and\n" \
" about the environment.\n" \
" -l List windows managed by the window manager.\n" \
" -d List desktops. The current desktop is marked\n" \
" with an asterisk.\n" \
" -s <DESK> Switch to the specified desktop.\n" \
" -a <WIN> Activate the window by switching to its desktop and\n" \
" raising it.\n" \
" -c <WIN> Close the window gracefully.\n" \
" -R <WIN> Move the window to the current desktop and\n" \
" activate it.\n" \
" -Y <WIN> Iconify (minimize) the window.\n" \
" -r <WIN> -t <DESK> Move the window to the specified desktop.\n" \
" -r <WIN> -e <MVARG> Resize and move the window around the desktop.\n" \
" The format of the <MVARG> argument is described below.\n" \
" -r <WIN> -b <STARG> Change the state of the window. Using this option it's\n" \
" possible for example to make the window maximized,\n" \
" shaded or fullscreen. The format of the <STARG>\n" \
" argument and list of possible states is given below.\n" \
" -r <WIN> -N <STR> Set the name (long title) of the window.\n" \
" -r <WIN> -I <STR> Set the icon name (short title) of the window.\n" \
" -r <WIN> -T <STR> Set both the name and the icon name of the window.\n" \
" -k (on|off) Activate or deactivate window manager's\n" \
" \"showing the desktop\" mode. Many window managers\n" \
" do not implement this mode.\n" \
" -o <X>,<Y> Change the viewport for the current desktop.\n" \
" The X and Y values are separated with a comma.\n" \
" They define the top left corner of the viewport.\n" \
" The window manager may ignore the request.\n" \
" -n <NUM> Change number of desktops.\n" \
" The window manager may ignore the request.\n" \
" -g <W>,<H> Change geometry (common size) of all desktops.\n" \
" The window manager may ignore the request.\n" \
" -h Print help.\n" \
"\n" \
"Options:\n" \
" -S List windows in stacking order (bottom to top).\n" \
" -i Interpret <WIN> as a numerical window ID.\n" \
" -p Include PIDs in the window list. Very few\n" \
" X applications support this feature.\n" \
" -G Include geometry in the window list.\n" \
" -x Include WM_CLASS in the window list or\n" \
" interpret <WIN> as the WM_CLASS name.\n" \
" -u Override auto-detection and force UTF-8 mode.\n" \
" -F Modifies the behavior of the window title matching\n" \
" algorithm. It will match only the full window title\n" \
" instead of a substring, when this option is used.\n" \
" Furthermore it makes the matching case sensitive.\n" \
" -v Be verbose. Useful for debugging.\n" \
" -w <WA> Use a workaround. The option may appear multiple\n" \
" times. List of available workarounds is given below.\n" \
"\n" \
"Arguments:\n" \
" <WIN> This argument specifies the window. By default it's\n" \
" interpreted as a string. The string is matched\n" \
" against the window titles and the first matching\n" \
" window is used. The matching isn't case sensitive\n" \
" and the string may appear in any position\n" \
" of the title.\n" \
"\n" \
" The -i option may be used to interpret the argument\n" \
" as a numerical window ID represented as a decimal\n" \
" number. If it starts with \"0x\", then\n" \
" it will be interpreted as a hexadecimal number.\n" \
"\n" \
" The -x option may be used to interpret the argument\n" \
" as a string, which is matched against the window's\n" \
" class name (WM_CLASS property). Th first matching\n" \
" window is used. The matching isn't case sensitive\n" \
" and the string may appear in any position\n" \
" of the class name. So it's recommended to always use\n" \
" the -F option in conjunction with the -x option.\n" \
"\n" \
" The special string \":SELECT:\" (without the quotes)\n" \
" may be used to instruct wmctrl to let you select the\n" \
" window by clicking on it.\n" \
"\n" \
" The special string \":ACTIVE:\" (without the quotes)\n" \
" may be used to instruct wmctrl to use the currently\n" \
" active window for the action.\n" \
"\n" \
" <DESK> A desktop number. Desktops are counted from zero.\n" \
"\n" \
" <MVARG> Specifies a change to the position and size\n" \
" of the window. The format of the argument is:\n" \
"\n" \
" <G>,<X>,<Y>,<W>,<H>\n" \
"\n" \
" <G>: Gravity specified as a number. The numbers are\n" \
" defined in the EWMH specification. The value of\n" \
" zero is particularly useful, it means \"use the\n" \
" default gravity of the window\".\n" \
" <X>,<Y>: Coordinates of new position of the window.\n" \
" <W>,<H>: New width and height of the window.\n" \
"\n" \
" The value of -1 may appear in place of\n" \
" any of the <X>, <Y>, <W> and <H> properties\n" \
" to left the property unchanged.\n" \
"\n" \
" <STARG> Specifies a change to the state of the window\n" \
" by the means of _NET_WM_STATE request.\n" \
" This option allows two properties to be changed\n" \
" simultaneously, specifically to allow both\n" \
" horizontal and vertical maximization to be\n" \
" altered together.\n" \
"\n" \
" The format of the argument is:\n" \
"\n" \
" (remove|add|toggle),<PROP1>[,<PROP2>]\n" \
"\n" \
" The EWMH specification defines the\n" \
" following properties:\n" \
"\n" \
" modal, sticky, maximized_vert, maximized_horz,\n" \
" shaded, skip_taskbar, skip_pager, hidden,\n" \
