OptiKey is able to simulate mouse input, meaning you can click, drag and scroll as if using a physical mouse. To open the mouse keyboard either select the 'Mouse' key which appears on most keyboards, or select the 'Mouse' key from the menu keyboard:
OptiKey 可以用来模拟鼠标输入，可以像使用一个物理鼠标那样点击，拖动和滚动。通过选择出现在键盘上的 “鼠标（Mouse）” 键，或者在菜单键盘上选择 “鼠标（Mouse）” 键，均激活模拟鼠标。

The mouse keyboard looks like this:
激活的模型鼠标如下：
The mouse keyboard appears in two forms; either collapsed as a single bar containing the most common mouse actions (left click, left double click, scroll down, scroll up, etc), or expanded showing all possible mouse actions. The expanded view is split into two categories:
模拟鼠标有两种显示方式：收缩成一行只包含最常用的鼠标操作（左击、左双击、滚动等），或者展开显示所有的鼠标操作。展开视图分为两类：
"Do at current location..."
在当前位置操作
These mouse actions occur at the current location of the mouse cursor, so you will not select the point at which to perform the action. There are special actions in this section to press and hold down the left, middle, and right mouse buttons, and then release them again later. This allows you to perform certain drag actions manually, e.g. move the cursor to a specific point, press and hold down the left mouse button, move the mouse down manually, and then release the left mouse button again.
鼠标操作仅对鼠标指针的当前位置有效，不需要考虑如何为鼠标选择生效点，此外还支持模拟鼠标的特别操作，比如按下并保持左、中、右鼠标按键，然后再把它们释放掉。这可以支持特定的鼠标拖动操作，例如将指针移动到特定位置，按下并保持鼠标左键，手动把鼠标向下移动，然后释放鼠标左键。
"Do at point..."
在单个点上操作
These mouse actions (including left, middle and right click, or scrolling) are performed by:
这些鼠标操作（包含左、中和右击，或者滚动）都是这样操作的：
-
Selecting the desired mouse action key (e.g. left click).
-
选择需要的鼠标操作键（比如左击）。
-
A large mouse cursor will be displayed to show where OptiKey is pointing. Direct your attention to the point where you wish to perform the mouse action and hold it there. A progress indicator will indicate that you are performing a selection. When the progress indicator completes your mouse action (a click, or scroll) will be performed at that point.
-
在 OptiKey 指向的位置会看到一个大的鼠标指针。注视你想执行鼠标操作的点，保持注视。此时会有一个进度指示器表明你正在进行一个选择。当进度指示器完成后，鼠标操作（一个点击或者滚动）将会在那个点执行。
When scrolling the number of wheel clicks to apply is indicated on the key labelled "Scroll by x clicks". Select this key to change the amount.
“点击多少下滚动（Scroll by x clicks）” 标签的按键表明点击多少下滚轮可以产生滚动。选择这个按键可以改变数量。
Using the magnifier
使用放大器“
To increase your precision when making mouse selections you can switch on magnification by pressing, or locking down the Magnifier key. You'll notice that the Magnification key cycles through 3 states; UP, DOWN, and LOCKED DOWN, before returning to UP, meaning the magnify functionality can be off, on for just the next mouse action, or permanently on. The progression as you select the key looks like this:
为了增加鼠标选择的准确性，你可以按下或者锁定放大按键（Magnifier）来打开放大功能。你会注意到放大键在三个状态切换：放大、缩小和锁定，在放大返回前，放大功能可以关闭，只为下一次鼠标操作打开，或者是持续打开。你选择这个按键的过程就像下面这样：

⇨
etc
Selecting a point becomes a two step process when using the magnifier:
在某位置上使用放大器需要经过两个步骤：
-
Direct your attention to roughly where you wish to click/scroll, at which point a magnified image of that area will be displayed.
-
注视你想点击或滚动的大概位置，那里会有一个区域的放大图像显示出来。
-
Direct your attention to exactly where you wish to click/scroll in the magnified image to perform the action at that point (or select outside the magnified area to cancel the action).
-
在放大的图像上，注视想点击和滚动的准确位置，并在那个点上执行操作（或者在放大区域外选择来取消这个操作）。
Dragging
拖动
Performing a Drag operation is slightly different as two selections have to be made after you select the drag key:
在你选择拖动（Drag）按键执行一个拖动操作时，稍微有点不同，因为需要有两个选择：
-
Select point one (this will be a two step process if the Magnifier key is pressed or locked down). This first selection will be where the mouse button is pressed and held down.
-
选择位置1（如果放大（Magnifier）按键按下或锁定，这里有两个操作步骤）。这是鼠标按键按下或者锁定的第一个位置。
-
Select point two (again, a two step process if using the magnify feature) - this will be the point to which the mouse cursor is dragged and released.
-
选择位置2（一样的，如果使用放大功能有两个步骤）——这将是鼠标指针被拖动和释放掉的位置。
Repeat last
重复上次操作
The 'Repeat Last' key allows you to repeat the last mouse action taken, which can be useful if you want to scroll down a long web page one scroll at a time, for example.
“重复上次（Repeat Last）” 按键允许你重复上一次的鼠标操作，例如，当你浏览一个长网页想要每次滚动一下时非常有用。
