Pasting into lists = keep indents consistent
, the light
Pasting any text, even without formatting, makes the list take on the unedited paragraph style. It's a bug, but it's not going to be fixed. The solution is to create a new style. However, there are two list types, and only the multi-level will work properly.

When indents change unexpectedly in a numbered or bulleted list, you have to verify that they have been set up properly. Click in the first level 1 item of the list and then click Home tab | Multilevel List | Define New Multilevel List (although the "new" part is misleading). Adjust the settings in the "Position" area as desired. You may have to click the More button to see all options.
