IDA Pro当前节点（The current node）

 　There are two concepts:the current node and the selected nodes.The node with the keyboard cursor is considered as the current node.If the user clicks on the graph background,the keyboard cursor will disappear and there will be no current node.In the absence of the current node,IDA uses the last valid address for the user commands(like rename and similar commands).For example,if the user invokes the'rename'command by pressing N and if there is no current node,IDA will still display the'rename'dialog box for the last valid address.

 Clicking on the node title will make the clicked node the current one.The keyboard cursor will be moved to the clicked node.Any selection of the disassembly text will be cancelled upon switching the current node.

 The default color for the title of the current node is dark gray.

 In addition to the obvious method of clicking with the mouse left-button to select the current node,IDA supports many other methods:

 -Clicking with the mouse wheel selects the clicked node and centers

 the clicked point in the window

 -Keyboard arrows can be used to move from one node to another.When

 the keyboard cursor reaches the node border and the user presses

 the arrow once more,IDA finds a node in the specified direction

 and makes it the current.

 -The Ctrl-Up key displays the list of nodes referring to the current

 node and allows jumping to them.The Ctrl-Down key does the same

 with the referenced nodes.

 -Pressing'5'on the keypad positions the keyboard cursor at

 the window center

 -Left-click on an edge makes one of its ends(source or destination)

 the current node.The node farthest from the click point is selected

 -Ctrl-click on an edge jumps to its destination

 -Alt-click on an edge jumps to its source

 Clicking with the mouse on the node text(disassembly listing)has the usual meaning:IDA will move the keyboard cursor to the clicked location.It is also possible to select the disassembly listing within one node.

 中文翻译如下：

 有两个概念：当前节点和选定节点。键盘光标所在的节点被视为当前节点。如果用户单击图形背景，键盘光标将消失，没有当前节点。在没有当前节点的情况下，IDA对用户命令（如重命名和类似命令）使用最后一个有效地址。例如，如果用户按N键调用'rename'命令并且没有当前节点，IDA仍将为最后一个有效地址显示'rename'对话框。

 单击节点标题将使单击的节点成为当前节点。键盘光标将移动到单击的节点。在切换当前节点时，任何汇编文本的选择都将被取消。

 当前节点标题的默认颜色为深灰色。

 除了使用鼠标左键单击选择当前节点的明显方法外，IDA还支持许多其他方法：

 ●使用鼠标滚轮单击选择单击的节点并将单击点居中显示在窗口中

 ●可以使用键盘箭头从一个节点移动到另一个节点。当键盘光标到达节点边界并且用户再次按下箭头时，IDA会在指定的方向中找到一个节点并将其设置为当前。

 ●Ctrl-Up键显示与当前节点相关的节点列表并允许跳转到它们。Ctrl-Down键执行相同的操作，但是对于引用的节点。

 ●在数字键盘上按下'5'将键盘光标定位在窗口中心

 ●在边缘上左键单击将其一个端点（源或目的地）设置为当前节点。离单击点最远的节点将被选择。

 ●Ctrl单击边缘跳转到其目标

 ●Alt单击边缘跳转到其源

 使用鼠标单击节点文本（汇编列表）具有通常的含义：IDA将键盘光标移动到单击位置。还可以选择一个节点内的汇编列表。
