Setting Your Undo Options - MapInfo_Pro - 2023

To set your undo options in MapInfo Pro:

1. On the PRO tab, click Options, and System Settings to open the System Settings Preferences dialog box.
2. 
   
   • Number of Undo Objects - Enter the number of objects (0 to 800) that can be undone. For example, if you specify the number 50, and then you perform a single editing operation that affects more than 50 objects, you will not be able to undo the operation. The number of undo objects can also affect the performance of MapInfo Pro.

     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.

     Note: 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.
   • 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 HOMEand SPATIAL tabs, the selected object(s) must be smaller in size than this setting.

3. Click OK to close the dialog and save your settings.
