This form element is used to hold a single line of arbitrary text.
During display, the contents of a text
input element is shown enclosed within "
#" characters, e.g.
Modification of the value is performed by activating the text input element which causes a helper window that contains a text input field and the two standard buttons to appear. The input field can be edited in the usual way and the resulting value may finally be accepted or discarded. Initially, the Accept button also gets the focus, so that invoking the Return key at any time causes the value to be taken over immediately.
