MsFreddie It comes with two 6.25u space bars (one has "Mykonos" printed on it) and one 6u space bar. They are all the same color. The left shift key is a 2.25u show in stock photos. There are two smaller shift keys included with the extras. One is 1.75u and the other is 1.25u.

MsFreddie It doesn't work for me either. I have not found another program, yet, that works with this keyboard.

MsFreddie You could use the keycaps from the K60 but there won't be enough caps since there are 60 keys on that and 77 keys on this. I have use Tai-Hao keycaps on my K77. Beware that there are keycaps sets that don't always accommodate the smaller numpad.

MsFreddie The spacebar is the standard 6.25u size.

MsFreddie standard, 2.25 size

MsFreddie Yes, there is not F1-F12. You have to push the FN at the bottom and then 1-10 to enable the function keys. This is not a 75% board or 100% board that would have dedicated function keys.

MsFreddie If you are able to, download their software. You may need look through the other question and answers to find it. The software was not able to work on my computer. For the Function Key look for the "FN" key, bottom row. Hold that down and at the same time press another key to enable its function. Both the FN and the other key must be pressed down at the same time.

MsFreddie None. As of right now the is no driver. The company does say it's coming soon, but not ETA on when that will happen.
