I use a wireless keyboard (logitech K800), but for those times when the battery is low I quickly connect the cable and continue using the keyboard without interruption or worrying about the low battery. Once it is charged I can go back to wireless. I do the same with my wireless mouse(logitech G900). This is a legitimate question by AnimeMania and I think the ability to swap between wired and wireless without interruption is a must have once you have experienced it.
I want to use the keyboard to control two different computers, one would be controlled via the cable and the second would be controlled via the dongle. I would have easy access to the wired computer but the dongled computer's ports would be hard to get to since it would be enclosed in a box, hence the wireless control needed. I would rarely need to access the boxed dongled computer, but the computer connected via the cable only (no dongle) would be used all the time. I would just remove the cable from the keyboard to be able to switch back and forth between the two computers. I am compiling a list of computer keyboards (
I am also looking for a wireless gaming mouse with the same capabilities) that will be able to do this when the time arises. Currently I have:
Keyboards
Kensington KP400 (Great price, but uses a regular battery, I was hoping for a rechargeable battery) this would be my first or second choice after this next keyboard, I will probably end up buying both and see which works better
Corsair K63 Wireless (Tenkeyless, I would prefer a full keyboard)
G-Cord Wireless Mechanical Gaming Keyboard (Impossible to find, seemed perfect)
A myriad of wireless mechanical gaming keyboards that would be very difficult to confirm before purchasing.)
Mice
Logitech G900 Chaos Spectrum (wireless gaming mouse)
Logitech MX Master 3 (not a gaming mouse)
