<title>Selecting Cells and Cell Ranges</title>
<para>
By selecting multiple cells at once, common operations can be
performed on all the cells which have been selected. These
operations include data entry, copying the cells, and multiple
other operations .
</para>
<warning>
<para>
Some operations cannot be done on selections of arbitrary
shape. For instance, <application>Gnumeric</application> could
not correctly reshape a worksheet following the deletion of a
discontinuous group of cells therefore such an operation is not
allowed. If users attempt an operation which cannot be performed,
a warning dialog will appear.

<title>Simple Selections</title>
<para>
The simplest selection involves a single cell. Simply clicking
with the left hand mouse button while the mouse cursor is over a
cell will cause that cell to become selected.
</para>
<para>
The selected cell is indicated by a dark double line with a small
square in the bottom right corner. The selected cell is the the
one that is currently in focus and will take any input for the
keyboard.

<title>Selecting Multiple Cells</title>
<para>
Several cells can be selected at once. When multiple cells are
selected, the selected cells are indicated with a light, "baby"
blue colour. When a single block of cells is selected, a double
black line will surround the selection, and all cells except the
first one to be selected will be shown in light blue.

<title>Continuous selections</title>
<para>
To make a continuous selection of cells, move the white cross
mouse cursor pointer to the cell at one corner of the block of
continuous cells, click and hold the primary mouse pointer on
that cell, drag the pointer to the opposite corner of the block
of cells and then release the mouse button. The block of cells
will now be selected.
</para>
<para>
The arrow keys can also be used to select a continuous block of
cells. To add cells in this manner, first select the cell in one
corner of the cell block with the primary mouse button, then
hold the <keycap>Shift</keycap> key and use the arrow keys to expand
the selection block.

<title>Discontinuous selections</title>
<para>
A discontinuous group of cells can also be selected, by selecting
cells or block of cells while holding down the
<keycap>Ctrl</keycap> key. To select a discontinuous group of
cells, first select a cell or a continuous group of cells as
explained above, then click and hold down the
<keycap>Ctrl</keycap> while selecting more cells. All of the
cells which are selected while the <keycap>Ctrl</keycap> key is
held down will be added to the selection. All selected cells
will be displayed with a light blue colour. Cells can be added
individually or as continuous blocks. This selection process is
additive with each selected cell added only once so selecting
cells twice or more simply adds those cells once to the selection.

<title>Advanced methods of Selection</title>
<para>
There are several ways to make selections using the keyboard
keys directly. These may be quicker than using the mouse
pointer. As explained above, the simplest of these uses the
<keycap>Shift</keycap> and <keycap>arrow</keycap> keys to make a
new selection.

<para>
To select an entire row of cells, press the combination of
<keycombo><keycap>Shift</keycap><keycap>space</keycap></keycombo>
keys. This is equivalent to pressing the row label button on the
left side of the sheet.
