Allows for resizing a window. If called from somewhere in a window or its border, then that window is resized. If called from the root window then the user is allowed to select the target window.

The operation can be aborted with Escape or by pressing any mouse button (except button 1 which confirms it).

If the optional arguments width and height are provided, then the window is resized so that its dimensions are width by height. The units of width and height are percent-of-screen, unless a letter 'p' is appended to one or both coordinates, in which case the location is specified in pixels. With a 'c' suffix the unit defined by the client application (hence the c) is used. So you can say

Resize 80c 24c

to make a terminal window just big enough for 80x24 characters.

If the width or height is prefixed with the letter 'w' the size is not taken as an absolute value but added to the current size of the window. Example:

# Enlarge window by one line
Resize keep w+1c

Both, width and height can be negative. In this case the new size is the screen size minus the given value. If either value is "keep", the corresponding dimension of the window is left untouched. The new size is the size of the client window, thus

Resize 100 100

may make the window bigger than the screen. To base the new size on the size of the whole fvwm window, add the frame option after the command. The options fixeddirection, direction and warptoborder are only used in interactive move operations. With fixeddirection the same border is moved even if the pointer moves past the opposite border. The direction option must be followed by a direction name such as "NorthWest", "South" or "East" (you get the idea). Resizing is started immediately, even if the pointer is not on a border. If the special option automatic is given as a direction argument, then the direction to resize is calculated based on the position of the pointer in the window. If the pointer is in the middle of the window, then no direction is calculated. The warptoborder option can be used to warp the pointer to the direction indicated. As with the automatic option for direction, the border to warp to is calculated based on the pointer's proximity to a given border. Also, if resizing is started by clicking on the window border, the pointer is warped to the outer edge of the border.

An alternate syntax is used if the keyword bottomright or in short br follows the command name. In this case, the arguments x and y specify the desired position of the bottom right corner of the window. They are interpreted exactly like the x and y arguments of the Move command. Actually, any of the options accepted by the Move command can be used.
