ctrl-z x c v in windows

The NEO developergroup payed attention to many of those. They also collected common sets of two or three letters from common applications. So the Smiley becomes just one roll over three buttons. I probably reap some benefits from that once I get back into Lateχ. In general I like to use tools that are optimized over my current horizon and can surprise me with thinks already put in way after I started to use them.

You can make the investment at any time you choose. Once you did the calculation changes (thanks to sunken cost) but before that its a matter of finding a convenient time space. Like when one is sick at home, or in holidays.

Iphone/ipad does not have Colemak or generic support for different layouts. Not sure about Dvorak.
