Selecting Edit | Spelling | Check All spell checks all visible fields of all records in the found set of the current layout.
To check all records in the table, be sure to select Show All Records first.
To restrict the spell check to only specific fields, create a layout where only the fields for which you want to check spelling are present.
Wonderful! You must be a truly beautiful person, Phil. Thank you. My eyes have been so glased over with new knowledge that I simply couldn't find that easy little solution.
Have a great weekend.
