"Many of us have blocks that we give many attributes with extensive information. An example is a titleblock I use that has 32 attributes. Most times I do a global edit, but to change a single attribute quickly in this block is a little time consuming untill you scroll through the dialog box to get to your attribute. A much faster way is to hold down CTRL and double click the attribute. This enables you to edit the attribute in place just like editing dtext."
Notes from Cadalyst Tip Patrol: This is a great time saving tip, even if there is only one text object to edit. You don't have to do much to change the text. Great tip.
