185: A server or a client does not necessarily implement full specifications

188: to send data unknown to peers. It is realized by exchanging the list of
189: supported @b{CMO} and @b{SM}. The list is called mathcap.
190: Mathcap is also defined as a @b{CMO} and the elements are 32bit integers

203: the check by a mathcap is done before data is sent.
204: If @code{"ox_check"} switch of @code{ctrl} is set to 0,
205: the check is not done.

2089: by dragging cursor with the left button of mouse
2090: from the upper-left corner to lower-right corner
2091: and then releasing it.

2093: area and whose size is determined so that the largest
2094: side of the new window has the same size of the largest side of
2095: the original window.
2096: If you wish to cancel the action, drag the cursor to any point
2097: above or left of the starting point.
2098:
2099: This facility is effective when @code{precise} button switch is
2100: inactive. If @code{precise} is selected and active, the area specified
2101: by the cursor dragging will be rewritten on the same window. This
2102: will be explained later.

2126: Will display, on the same window, a new area enlarged by 10 times
2127: as large as the current area for both width-direction and
2128: height-direction. The current area will be indicated by a rectangle
2129: placed at the center. Area specification by dragging the cursor will

2132: When selected and active,
