Note below.In Bulk Edit tools, a change is only applied to displayed rows that are selected. See Note below.
Click the check box at the left end of each row to select (
) or clear (
) it.
Alternatively, click the check box button 
at the top of the left column, and then select one of these commands:
Select All
This selects all displayed rows ().
Then, clear the check box for each row you do not want to change.
Clear All
This clears all displayed rows ().
Then, select the check box for each row you want to change.
Example: Initially, all rows are selected, but you want to change only a few rows. Fewer mouse clicks are needed if you clear all the rows, and then manually select the rows you want to change.
Toggle
This reverses which displayed rows are selected and which are cleared.
Example: Initially, all rows are selected. You begin clearing rows you do not want to change, but realize that you are clicking many rows. At this point, to save your work and reduce the number of necessary mouse clicks, click Toggle. Then manually select the rows you want to change.
NoteIn Lexicon, each row in the window may contain an entry, one or more senses, one or more allomorphs, and so on. The primary sort affects this: If you sort on entry-level data, each row contains one lexical entry; if you sort sense-level data, each row contains one sense, and so on. So, the number of rows changes in the Status bar.
