This gives a summary of the mouse operations available in PipeDream. It is intended as a reminder rather than an exhaustive reference. For more information refer to the section called Caret Movements in the Reference Guide.
Many of these mouse operations are described interactively in the RISC OS Help application when used in conjunction with PipeDream.
To open a new PipeDream window, click
on the PipeDream icon on the icon bar.With the pointer in a PipeDream window, click
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.

on the command name. This carries out the command and removes the menu from the screen. If you click , the menu remains on the screen.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.
Always use the
button to position the caret within cells. Normally the caret will be positioned in the cell you are pointing at. However, if there is a text cell to the left of the cell you are pointing at, PipeDream will position the caret in the cell to the left. This prevents you accidentally typing in columns to the right of where you expected.If you really want to position the caret to the right of a text cell, hold down Ctrl when you click . Alternatively a single click in the column border will move the caret into that column.
To mark a block, hold down
and drag from the top-left of the block to the bottom right.To mark complete columns, drag
across the column borders.To mark complete rows, drag
down the row borders.To mark one complete row, double-click

in the column border.To mark the whole document, click
in the Mark Block box at the intersection of the row and column borders.To clear any marked block, click
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
. The marked block will now end where you click. The starting point will remain the same.Position the pointer on the scroll arrow and click
to scroll one line in the direction of the arrow. Hold down to continue scrolling. Click 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
. The next windowful of the document will appear. Click 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.
