One of the most unique and fun features of the UHK is built in mouse navigation, so let's give it a spin!
Moving the pointer
Hold the Mouse key, and press I, J, K, or L to move the pointer upwards, leftwards, downwards, or rightwards.
Please note that mouse movement may be very fast or slow on your system. It's highly dependent on your operating system and its settings. If you're on a Mac, mouse movement is probably very slow and scrolling is very fast. Don't worry, you'll be able to fine tune the speed and acceleration of the mouse in Agent.
Press Mouse + F to left click. Here's a widget to practice.
Click to change color
Double click to change size
Hold to rotate
Now apply what you've learned in order to drag Source into Destination!
Mouse + S invokes right mouse click. Try it to activate the context menu of the browser.
Mouse + D invokes the middle mouse click. Let's give it a try!
Middle click to rotate
Hold Mouse, and press Y, H, U, or O to scroll upwards, downwards, leftwards, or rightwards.
Mac users, the upwards and downwards scrolling keys of your UHK are not reversed, but rather it's the reverse scrolling feature of OSX. You can disable it in System Preferences, or switch these keys in Agent.
You can practice horizontal scrolling on the following picture.
Acceleration and deceleration
While holding Mouse and moving the pointer or scrolling, you can also hold the Accelerate and Decelerate keys to affect mouse speed. Acceleration is quite useful when moving the pointer to the opposite corner of the screen or scrolling through long web pages quickly. Deceleration is handy for precision control.
Locking the mouse layer
Holding Mouse is exhausting in the long run, so you can double-tap it to lock it. Then tap it again to unlock it.
When the mouse layer is locked, the "mouse" text on the LED display lights up, so you can always see if it's enabled.
With the above alternative click keys, you can lock the mouse layer, then mouse around only by using your right hand.
