Small mobile accessory keyboard

Ideal for my small apartment. If I fiddle eg in the kitchen while listening to music or sitting on the couch and look at a movie, I grab this keyboard which I run in addition to my Mac Mini and so can skip songs , fast forward and rewind, pause, make the sound louder and softer, etc., to get up every time and without running the Mac. So for me, something like a remote control and a much cheaper solution than me to purchase an iPad or iPhone (for such purposes).

That one does not require batteries for this keyboard, is another invaluable plus. Although it takes when a key press first second until the Mac responds, and sometimes (rarely) I have the keyboard and off briefly and then on again to make it work, but I can live fine.

One must however be clear that some buttons missing in comparison with a large keypad, as Page Up / Down, Home / End, remove (instead fn-backspace key) and the numeric keypad. Also missing the two buttons for forward and backward jumping and coils (>), but Alt-Command-arrow-right and -left do the same.
