Pitney Bowes MapInfo Professional - Manual (Page 95)

The default is 10 objects. You can set it from 0 to 800. Setting the number of objects to 0 deactivates
the system. After you use the Undo option, the system toggles to Redo.
You cannot use the Undo capability for the following operations: Revert, Save, Save As,
or Modify Table, or any operations whose effects are primarily cosmetic. Note:
• Memory Size for Undo - Indicates the memory size in bytes for Undo operations. Maximum is
10,000,000 bytes. The default is 1,000,000 bytes; increasing this entry may result in slower response
time.
For Undo to be available on the Edit menu, the selected object(s) must be smaller in size than
this setting.

Setting Your Color Defaults
When creating a thematic map, you need to distinguish between objects in different thematic layers.
When you create a new thematic layer, MapInfo Professional chooses the initial colors and patterns
based on this setting. Either a range of solid colors or a range of black and white patterns is used.
Changing the color default settings does not affect existing maps or graphs.
1. On the Options menu, point to Preferences and click System Settings to open the System Settings
Preferences dialog box.
2. In the Color Defaults panel, choose one of the following:
• Monitor Setting - Determines if your monitor is color or black and white and then uses either color
or gray scale fill patterns. This is the default setting.
• Black & White - Use this setting to view and print your thematic map in gray scale when working
on a color monitor.
• Color - Use this setting to work on a black and white monitor but print in color on a color printer.
3. Click OK to close the dialogs and save your settings.
Setting Show Guides when Docking Windows
You can dock windows, such as the Layer Control and Table List, and some tools, such as Named
Views and Catalog Browser, to the sides (top, bottom, left, and right) of MapInfo Professional. The
windows are in a fixed position when they are docked and can share the same space-you may dock
multiple windows to the same side of the screen. When the windows are not docked, they are floating
and can be moved anywhere in the window.
There are visual guides that look like arrows that display by default to help you when docking a window
or a tool. You can drag the window or tool to one of the arrows to dock it at that location. These visual
guides display by default. You can show or hide them in MapInfo Professional using a software preference.
To show or hide visual guides when docking a window in MapInfo Professional:
1. On the Options menu, point to Preferences and click System Settings to open the System Settings
Preferences dialog box.
2. Select the Show Guides when Docking Windows check box to display visual guides, in the form
of up, down, left, and right arrows, to help you when docking windows in MapInfo Professional.
Clearing this checkbox hides these guides.
3. Click OK to close the dialogs and save your settings.
Setting Your Date Window for Two-Digit Years
MapInfo Professional converts two-digit input into four digit years using the current century for the dates
(so that 14 becomes 2014). If your data includes dates in the 1900s, then you can turn on date windowing
to select a pivot year below which to use the previous century. If you specify the number 50 as the pivot
