cover sheet

 By cheking View ->cover sheet in Menu Bar, one can hide a page under Presentation Mode. One of the folllowing cover type is indicated.

bottom: cover bottom
right: cover right side
left: cover left side
bottom + right: cover bottom and right side
bottom + left: cover bottom and left side

At first, the whole page is hidden by a cover sheet. The cover sheet can be moved by the mouse or by using pause special. If one moves to the former page, then the page has no cover sheet and the status of the original page is kept.

1. Under pressing the left button of Mouse, change the shape of the mouse cursor into the up-down/right-left arrow by clicking the right button of the mouse if necessary. If the whole page is in a screen, the clicking is unnecessary.

If the boundary of the cover sheet is in the screen, the cursor jumps to the position. Then moving the mouse under pressing the left button of the mouse implies the moving of the cover sheet. If releaseing the left button of the mouse, the mouse corsor jumps to the original position.

2. If \special{pause} is written in the source text of TeX, the clicking [Space] key moves the cover sheet to the position where the special is written.

The click of [Space] key implies to move the cover sheet to the next position where \special{pause} is written. If there exist no \special{pause} after there in the page and there exists a part hidden by the cover sheet, the cover sheet will be moved to the position no part of the page will be hidden.
On the other hand, if there exists no \special{pause} after there in the page and there exists no part hidden by the cover sheet, then the next page is shown.
Then the cover sheet is at the first position indicated by the first \special{pause} in the next page or the whole page is hidden by the cover sheet (or no part is hidden under On for Pause) if there exists no \special{pause} there.

See an example of the usage of pause special.

3. Special functions are attached to the following function keys uner Presentation Mode(The functions can be attached to other keys [Key]).

F5 On : Use cover sheet
F6 Off : Don't use cover sheet
F7 Suspend : Suspend to use cover sheet
F8 Return : Return to the place where the original cover sheet exists
F9 On for Pause : Similar as F5 but the cover sheet is at the position where no part of the page is hidden if no \dviout{pause} exists in the page.

By the above Suspend, the current place is recorded as "the place where the original cover sheet exists"

Under suspending to use cover sheet, if the place to display coincides with "the place where the original cover sheet exists", then the cover sheet is again used and the suspension is stopped.

The above Return means to return to "the place where the original cover sheet exists" and to stop the suspension.

The above OFF or jump by HyperTeX is done after performing the above Suspend.

Remark: Turning the wheel of IntelliMouse with pressing it means to move to anothe page (cf.Q_V12). In this case, if the left mouse button is also pressed, then the movement to the next page can be done without suspending the cover sheet, that is the same result as clicking [Space] key.

Remark: Successive pushing of [Space] key for a dvi file without any \special{pause} under Presentation Mode with the cover sheet implies the following change of the preview:
a page hidden by the cover sheet -> no part of the page is hidden by the cover sheet -> the next page is shown with covered by the cover sheet ->...
If On for Pause is used, the avove "page is shown with covered by the cover sheet" is skipped.
