Scrolls the virtual desktop's viewport by horizontal pages in the x-direction and vertical pages in the y-direction or starts interactive scrolling of the viewport. Either or both entries may be negative. Both horizontal and vertical values are expressed in percent of pages, so

Scroll 100 100

means to scroll down and right by one full page.

Scroll 50 25

means to scroll right half a page and down a quarter of a page. The Scroll function should not be called from pop-up menus. Normally, scrolling stops at the edge of the desktop.

If the horizontal and vertical percentages are 100 or more and are multiplied by 1000 then scrolling wraps around at the edge of the desktop. If

Scroll 100000 0

is executed over and over fvwm moves to the next desktop page on each execution and wraps around at the edge of the desktop, so that every page is hit in turn.

If the letter 'p' is appended to each coordinate (horizontal and/or vertical), then the scroll amount is measured in pixels.

Without arguments or if the option reverse is given interactive scrolling takes place. The viewport scrolls as the mouse is moved. With the reverse option scrolling is done in opposite direction of the mouse movement, and without it scrolling in the same direction as the mouse.

The binding

Mouse 1 A CM Scroll reverse

gives an effect of grabbing and dragging the viewport with button 1 if Control and Meta is pressed.
