The more I see it, long travel keys don't make sense to me (Cherry MX= 4mm) they slow me down...
In other words
a perfect keyboard for me would be similar to a Cherry MX (Blue) with 1mm to 2mm key travel (similar to rubber dome), but with a click sound (volume and frequency) of a mouse click. .
When it comes to size, the HHK Lite 2, would seem good for me (needs to have the inverted T arrows). Not sure about the CTRL and right Fn key, though. I'll order one now, to test...

I don't expect to have big issue pressing Fn for the F keys and maybe the Pg Up/Dn, but BkSpace and Del might be an issue (I use them both, since leaving the Commodore 64!) and having to Fn those might be an issue...
