4.3.5 Other Table Editor commands
Undoing/redoing changes
You can undo and redo all editing operations in the Matrix
Editor. To undo the last operation, click the undo icon on the toolbar, or
select Undo from the Edit menu. To redo the most recently undone
action, click the redo icon on the toolbar, or select Edit | Redo. The
menu items on the Edit menu show the name of the operation to undo or
redo.
To perform multiple levels of undo/redo operations at
once:
| 1) | Select
Edit | Undos/Redos... to see the list of possible
operations. |
| 2) | Select
the last step you want to undo/redo. |
The
number of undo/redo steps is unlimited within a transaction, but committing or
abandoning will reset the undo/redo buffer. Also please note that the undo/redo
buffer is global for the whole of MetaEdit+. As it is possible to have the same
conceptual object in many graphs, this means that changes made in one editor can
be undone/redone from another editor or from the MetaEdit+
Launcher.
Cutting, copying and pasting objects
To cut or copy an object:
| 1) | Select
the object to cut or copy by clicking a row in the
table. |
| 2) | Select
the Cut or Copy command from the Edit menu, pop-up menu or
toolbar. |
Paste objects by selecting
Paste from the Edit menu, pop-up menu or toolbar. Pasting objects
simply creates new representations of the same objects: if you change a pasted
object’s properties, you are also changing the original object. Any
relationships or roles between the objects are ignored when pasting in the Table
Editor.
If you need to have true copies instead, breaking the
links with the original elements, use Paste Special. To invoke Paste Special,
select
Edit | Paste Special.... A dialog will open for defining the depth
of the copy (as in
Figure
4–48).
Figure 4–48. Paste Special.
The options in the Paste
Special dialog are as follows:
 | No
Copy provides the same results as the normal Paste command, i.e. only a new
representation but of the same
object. |
| Copy
to Depth copies the contents of the elements down to the level entered into
the number field. Elements below that level are shared with the
original. |
| Deep
Copy makes full copies, i.e. works like Copy to Depth to an
unrestricted level. |
More details about
copying to various depths are given in the description of the Replace Tool in
Section
3.3.5.
Setting selection type
The Table Editor provides two modes of selection within the
table: by row or by cell. The mode can be set by toggling
View | Select by
Cell. By default, the selection highlights the whole row. When the
Select
by Cell is toggled on, the selection will focus on the specific cell on the
row. Furthermore, when the cell-specific mode is active, opening properties for
the property that contains an object will bring up the property dialog for that
contained object (or start creating it, if the property is empty). Holding down
the
Alt key while opening will override this and open the property dialog
for the containing object (i.e. show all
properties).
