well my 2-year old thinkpad does not recognize 3 finger touch. I would much rather have a uniform cut-copy-paste command rather than wait for some funky hardware support .. or upgrade.
If there was some magical way to get gnome-terminal, vim and firefox/chrome honor a universal cut-copy-paste shortcut... then I'm golden. This is more of a political than a technical problem.
Yes, I know I can remap keys in firefox, in gnome-terminal and browsers. But then they dont work in skype.. or something else. I would pay good money if there was a kickstarter around this.
