With a text box, you can display, enter, or edit a alphanumeric text or numeric value. Text box come in different flavors displayed in Table 1.
Numeric text boxes may allow to enter and display null values. To enter a null value in a text box that supports it, select the whole text in the input box and hit the Del key. Doing so in numeric input text boxes that do not support null values will set the value to zero. Numeric text boxes may show the unit of the number.
When receiving focus the text in a text box is either fully selected or the caret is placed at the end of the text. The decision of this behavior was done with the intended usage in mind.
