Run OptiKey for the first time and it will be displayed with a dark theme, position itself at the top of your screen (docked), and ensure that any other running applications are positioned in the remaining free space. By default it uses your mouse cursor position for input and selecting a key is performed by hovering over a key for about 1.5 seconds.
OptiKey 首次运行将以黑色的主题固定显示在屏幕的顶端，并确保其他正在运行的程序显示在空闲区域而不被其遮挡。默认情况下在光标所在位置输入，移动到一个键位上 1.5秒 即可以选中。
Try it out - move your mouse cursor over OptiKey and notice how the current key under your cursor is highlighted with a red outline. Keep the mouse cursor over a single key and you'll see an indication of your selection progress on the current key. This is a method of selection called "fixation" or "dwell" and requires you to keep your attention (the cursor) on each key for an amount of time in order to select the key.
尝试一下 - 移动光标到 OptiKey，注意光标下的按键会被一个红色边框高亮。把光标停留在某一个键位上面时，可以看到当前键位的选择进度。这种选择方式称为定位 (“fixation"或"dwell”)，定位按键时需要通过在光标位置，注视并聚集一段时间。
Complete a selection over a letter and it will be pressed and appear in the "scratchpad" at the top. You will also notice that some auto complete suggestions will appear above the scratchpad. Keep selecting letters to type a whole word, or select one of the auto complete suggestions to complete your word.
完成一个字母的选择后，其会被按下并显示在顶部的 “提示框（scratchpad）” ，提示框里可以看到单词的自动联想，此时可以继续输入字母或从提示框中选取单词。
If you make a mistake you can use the backspace key to delete your last selection:
输入错误时，可以使用退格键（backspace） 删除最后一个选择字母：
or the BackMany key to delete the last whole word: 或者使用 BackMany 键删除最后输入的整个单词
That's all there is to start selecting keys and typing words! 以上就是使用 OptiKey 进行选择与输入的所有操作了!
