# 控件属性

打开用于编辑选定控件属性的对话框。

要访问此命令...

Open context menu of a selected form element - choose Control.

控件

You can only call the Properties dialog when in the Design mode with a control selected.

请注意，在属性对话框中输入数据时，某些下拉组合框允许进行多行输入，这包括所有可以输入 SQL 语句的字段，以及文字框或标签字段的属性。可以打开这些字段并在打开的列表中输入文字，还可以使用以下快捷键：

键 | Effect
OptionAlt +Down Arrow: | Opens the combo box.
OptionAlt +Up Arrow: | Closes the combo box.
Shift+Enter | 插入新行。
Up Arrow | 将光标置于前一行。
Down Arrow | 将光标定位到下一行中。
Enter | 结束在字段中的输入并将光标置于下一个字段。

As with list boxes or combo boxes, you can open or close the list with a mouse click at the arrow on the right end of the field. However, the input here can be entered either in the opened list or in the top text field. An exception is the properties that expect a list representation, for example, the property "List Entries", which can be set for the control fields List Box and Combo Box. Here, you can only edit the entries when the field is opened.
