A:AnswerNot sure what the range is for a tower computer, I use the keyboard for my Ipad and my Iphone. I had intended to use with my work laptop but had connectivity issues where the laptop would recognize the keyboard but would not work. I decided to keep and use if with my other apple products.
A:AnswerYes, although Windows is really bad for bluetooth. When you use a Mac with bluetooth keyboard, you barely notice, but on Windows, bluetooth is prone to crashing, you loose connectivity, there might be lag to connect shortly after boot, etc.
The keyboard is amazing, but mind the limitations of the platform you use it with.
A:AnswerThe characters and symbols can be accessed along the number, and shared command keys. Use "shift" as you would on any keyboard, to use the alternative key commands. This K380 even has split key commands for Apple or Windows software.
A:AnswerYou didn’t miss it. They have a Mac version of this keyboard but it’s only available in white. Not sure if that one has them. I use mine with my Mac without issues. Some features still requires use of Mac keys.
