The Mouse

The mouse is used to set point, mark and the block.

Button 1 in the cell area moves point
Button 1 on vertical grid line adjusts column width
Button 1 on horizontal grid line adjusts row height
Button 1 on grid line crossing does autofill
Button 2 in the grid inserts the current selection
Button 3 (or Shift - Button 1) in the grid extends the selection
Button 1 in column header sets block to the clicked column
Button 1 between column headers adjusts column width
Double-click button 1 in column header automatically adjusts column width
Button 3 in column header extends the selection
Button 1 in row header sets block to the clicked row
Double-click button 1 in row header automatically adjusts row height
Button 3 in row header extends the selection

Moving the mouse in the grid with button 1 pressed defines the selection.

Mice with fewer than 3 buttons can be used by changing the app-defaults.

This behaviour is consistent with most other X applications.

The selection can be cleared directly by calling the function (unset-block) (Block - Unset Block on the menu) or indirectly by selecting something else in another part of the grid, in another instance of Siag or in another X application.

Autofill

Autofilling works by placing the pointer over a grid line crossing, pressing down, dragging to the lower right corner of the area you want to fill and releasing. The neat thing about this is that you can automatically get series of values by following this example:

Enter 2 into cell A1
Enter 5 into cell B1
Position the pointer over the lower right corner of A1, so that the pointer changes shape
Click down and hold
Move the pointer to F1
Release

The area is filled with 8 in C1, 11 in D1, 14 in E1 and 17 in F1.
