1.2. 选择和模式(OLEX2使用手册)

原文如下：

Selections and mode

You can modify the properties of any element of your structure model using the either the Olex2 GUI or by issuing command-line commands. For example, you can change the currently assigned atom type by right-clicking on and atom, and selecting the ‘atom type’ menu, or you can type:

>>name O

to change an atom or Q peak to an oxygen atom. Typically, some atoms must be selected before commands like this make sense. Selected objects will turn green in Olex2 and you can add more items to the selection by simply clicking on them. You can also draw a rectangle around items by pressing the left hand mouse button while holding down the SHIFT key.

In contrast to selections: when a ‘mode’ is active (‘Olex2 is in a mode’) then something will happen to the objects that are being clicked on next. You know that you are in a mode, because the mouse symbol will have changed from a pointer (arrow) to the hand symbol, and there will also be an orange box in the bottom right hand corner of Olex2, detailing which mode you are currently in.

1.2. 选择和模式

可以通过Olex2 GUI或命令行指令来修改结构模型的任意元素的属性。例如，你可以通过在原子上右键单击并选择“atom type”菜单来更改当前指认原子类型，或者你可以键入：

>>name O

将一个原子或Q峰更改为氧原子。通常，此类指令在起作用之前必须选择一些原子。在Olex2中，选定的对象将会变成绿色，只需要单击它们即可将更多项目添加到选择中。你也可以通过在按住SHIFT键的同时按下鼠标左键，在项目周围绘制一个矩形类进行选择。

与选择相反：当某种“模式”处于激活状态(“Olex2处于某种模式”)时，下一个被单击的对象将会发生一些事情。你可以通过以下现象知道你处于某种模式，鼠标指针(箭头)更改为手形符号，并且在Olex2右下角还会有一个橙色方框，详细说明你当前处于的模式。
