Kinda. I had to plug in a second mouse, which I threw behind my desk, otherwise that pointer always stayed in middle of the display. With the second mouse plugged in, I can force that pointer way into the corner. I don't use it. But I do sometimes attach the keyboard to it, so it's separated from the primary pointer. Then I can use the primary pointer and keyboard separately. When split, I still technically only have one focused window, but the keyboard doesn't move to it. It stays in the editor unless I move it using the keyboard.

The hotkey is used to switch the pointer the keyboard is attach to.
