Using Lock Text is particularly useful if you want to select and move objects but not make any changes to the text. You can single-click the object to select it, but you must double-click the caption or text to make changes.Includes buttons, check boxes, date/time fields, decimal fields, signature fields, drop-down lists, image fields, list boxes, numeric fields, paper forms barcodes, password fields, radio buttons, and text fields.The lock commands are useful in situations when you have finished formatting specific objects in the form design and want to continue working with other types of objects. For example, your form includes a large number of text field objects, as well as text objects that provide instructions about filling the form. You have positioned and formatted all the text objects and need to apply a different font to the text field objects. You can easily do this by locking the text objects and then using Edit > Select All Fields to select all the text field objects at once and then change the font.
