!PipeDream/!Help

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

%C%%H2%PipeDream  Help file

 
This file gives a summary of the mouse operations available in 
PipeDream 4.  It is intended as a reminder rather than an exhaustive 
reference.  For more information refer to the section called Caret 
Movements in the PipeDream 4 Reference Guide.

%C%%H2%Mouse operations

Many of these mouse operations are described interactively in the RISC 
OS !Help application when used in conjunction with PipeDream 4

%H2%Opening a Pipedream window

To open a new PipeDream window, click Select on the PipeDream icon on 
the icon bar.

%H2%Bringing up menus and choosing commands

With the pointer in a PipeDream window, click Menu to bring up the top 
level menu.

To bring up a sub-menu, drag the pointer over the arrow to the right of 
the menu name.

To choose a command, click Select on the command name.  This carries 
out the command and removes the menu from the screen.  If you click 
Adjust, the menu remains on the screen.


%H2%Loading documents

To load a PipeDream document, either double-click on its icon, or drag 
its icon onto the Pipedream icon on the icon bar.

To insert a file at the caret position, drag the file's icon into the 
window.


%H2%Positioning the caret

Always use the Select key to position the caret within slots.  Normally 
the caret will be positioned in the slot you are pointing at.  However, 
if there is a text slot to the left of the slot you are pointing at, 
PipeDream will position the caret in the slot to the left.  This 
prevents you accidentally typing in columns to the right of where you 
expected.

text to left

So, if you click above between the v and the ^, PipeDream will place 
the caret after the word left.

If you really want to position the caret to the right of a text slot, 
hold down Ctrl when you click Select.  Alternatively a single click in 
the column border will move the caret into that column.  So if you 
click between the v and ^ above the caret will go into column A.  If 
you then click on the D in the column border at the top of the window 
PipeDream will move the caret into column D.


%H2%Marking blocks

To mark a block, hold down the Select button and drag from the
top-left of the block to the bottom right.

To mark complete columns, drag Select across the column borders.

To mark complete rows, drag Select down the row borders.

To mark one complete row, double-click Select in the row border.

To mark one complete column, double-click Select in the column border.

To clear any marked block, click in the Mark Block box at the 
intersection of the row and column borders.

To mark the whole document, click Select in the Mark Block box at the 
intersection of the row and column borders.  

To adjust a marked block after marking it, move the pointer to the 
point at which you now want the block to end and click Adjust. The 
marked block will now end where you click. The starting point will 
remain the same.

%H2%Entering slot references into the editing line

To enter a slot reference into the editing line whilst you are editing 
an expression, click Select in the slot.  The slot can be in the 
current window or in another, in which case you will insert an external 
reference.

%H2%Scrolling the window

%H2%Up and down

Position the pointer on the scroll arrow and click Select to scroll one 
line in the direction of the arrow.  Hold down Select to continue 
scrolling.  Click Adjust to scroll in the other direction.  The caret 
always remains within the PipeDream window, staying as near as possible 
to its original position.

Position the pointer on the darker part of the scroll bar (above the 
slider to scroll up, below the slider to scroll down) and click Select.  
The next windowful of the document will appear.  Click Adjust to scroll 
back the other way.  The caret always remains within the PipeDream 
window, moving, if necessary, to the point nearest to its position 
before scrolling.

To move a long distance up or down drag the slider in the vertical 
scroll bar.

%H2%Left and right

Click on the left and right arrows in the horizontal scroll bars to 
move one column left or right.

Click in the dark grey area of the scroll bar to move the window one 
windowful left or right.
