|
|
A cell can be shown either isolated (this is the default, if the cell is the current cell), |
|
|
embedded (as a subcell of the current cell) or as the current cell in the context of another direct or |
|
|
indirect parent cell. In the latter mode, the cell is highlighted while the context cell is shown |
|
|
in dimmed or another, user-defined color. |
|
|
</p><p> |
|
|
To highlight a cell in a context, first choose the context cell. Then select a shape or a cell instance |
|
|
within the cell to show in the context and choose "Descend" from the "Display" menu or press "Ctrl+D". Now, the first child |
|
|
cell leading to the selected shape is highlighted, while the surrounding shapes of the parent cell (the |
|
|
previous current cell) is shown in dimmed colors. Choose "Descend" repeatedly to descend further into the |
|
|
hierarchy until the selected shape or instance is on the level of the current cell. The current cell is |
|
|
show underlined in the cell tree, while the context cell is shown in bold font in the cell tree as usual. |
|
|
</p><p> |
|
|
The reverse of this operation is "Ascend" (or "Ctrl+A") available from the "Display" menu. |
|
|
</p><p> |
|
|
The way how the context layout is shown can be adjusted in the setup dialog on the "Background" tab. |
