%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.
