+REQ_VALIDATION Validate field.
+.TE
+.PP
+If the second argument is a printable character, the driver places it
+in the current position in the current field. If it is one of the forms
+requests listed above, that request is executed.
+.SS Field validation
+The form library makes updates to the window associated with form fields rather than
+directly to the field buffers.
+.PP
+The form driver provides low-level control over updates to the form fields.
+The form driver also provides for validating modified fields to ensure that the contents
+meet whatever constraints an application may attach using \fBset_field_type\fP.
+.PP
+.PP
+You can validate a field without making any changes to it using
+\fBREQ_VALIDATION\fP.
+The form driver also validates a field in these cases:
+.bP
+a call to \fBset_current_field\fP attempts to move to a different field.
+.bP
+a call to \fBset_current_page\fP attempts to move to a different page of the form.
+.bP
+a request attempts to move to a different field.
+.bP
+a request attempts to move to a different page of the form.
+.PP
+In each case, the move fails if the field is invalid.
+.PP
+If the modified field is valid, the form driver copies the modified
+data from the window associated with the field
+to the field buffer.
+.SS Mouse handling
+.PP
+If the second argument is the KEY_MOUSE special key, the associated
+mouse event is translated into one of the above pre-defined requests.
+Currently only clicks in the user window (e.g., inside the form display
+area or the decoration window) are handled.
+.PP
+If you click above the display region of the form:
