Hi,A2 Experts

the  A2 has some innovative operations, but some not suit for me,
if I want to use it as a develop platform, has to custom it for my old habits;

1,the first question is font , I have ask Felix for it by email,
though not too understanding his answer, but now the question seems gone, not so unbearable;

2, the second question is double-click action;
I am not used to double-clicking the action that triggers the command.
I want to change it from "double-click" to "ctl"+"double-click" to trigger command,
with double-click to select text words;

I tried to solve the second problem several times, but failed.
This stop me from continuing to explore A2.

how to do it? Who has such a solution?
thanks in advance
