Pitney Bowes MapInfo Professional - Manual (Page 76)

Use the Ctrl key with the Info button to toggle through all selectable layers and access
overlapping objects. Note:
When you click a map location using the Info button where two or more selectable map objects overlap,
the data tied to the objects on each layer display in the Info tool window. If you do not want the information
for all layers to display, turn off Selectable for those layers in the Layer Control window.
You can also view an object's label expression in an InfoTip when you use the Select, Info, or Label
buttons. InfoTips work very much like ToolTips. Using one of these tools, place your cursor over an
object. An InfoTip displays the label expression for the object in the topmost selectable layer. To set
InfoTips for a particular layer, adjust the Selectable attribute in the Layer Control window so that the Tips
display for the layer you want. InfoTips are active by default, but you can turn them off in the Map window
preferences (on the Options menu, point to Preferences and click Map window).
Selecting Objects in a Layer
If you only want to select objects for further analysis rather than edit the objects, make the layer selectable.
More than one layer can be selectable at a time. If a layer is editable, it is also selectable.
Many MapInfo Professional functions require that map objects be selected before performing the particular
operation. To use the Select button, Label button or Info button you must first make the layer selectable.
Unlike the editable feature, more than one layer may be selectable at the same time. You may, however,
only select from one layer at a time.
The Select button selects objects from the topmost Selectable layer. To select an object that is not in
the top Selectable layer, you can turn off the Selectable option in Layer Control for every layer above
the layer you want to select from by selecting a layer's Selectable icon to deactivate it. Alternately,
you can leave all layers Selectable and use the Ctrl key in combination with the Select button to cycle
through each Selectable layer.
The instructions for making a layer editable are the same, except that you select Editable On/Off
instead.
Note:
• For instructions on making objects in a layer selectable, see Selecting Objects in a Layer in the Help
System.
