Re: [Denemo-devel] 2-key shortcuts

[Nils Gey]

Hello,

First I think its a no-go to change anything in Denemo (or any other computer 
program) to key-release triggers (while nothing happens on press). 

Second I have to say I am not really sure if this kind of shortcut (normal keys 
as modkeys) has any benefit over the normal modkey+basic key followed by 
another basic key which can be seen all over the linux world, especially in 
other GNU projects like Screen or Emacs.
If you have to press another modifier (like numlock) to turn this behaviour on 
and off it gets far away from the initial goal to make complex and an a huge 
amount of commands easily available.

I personally don't use letter keys to enter notes, too. But there has to be 
away to use the letter keys for notation and use them for other things, too. 
And I think these should only be modkey combinations and sucessive key presses.

Nils
