3 quick questions from a new user

[Colman G]

1. Is it possible to edit tags in Yojimbo? That is, can I go back and  
correct/ change the name of a tag that I've already created &  
assigned to items?

2. In the Quick Input panel, if I've tabbed into a note's main  
content field, is it possible to "Create" that item from the  
keyboard? Or must I go to the mouse to click on "Create"?

3. Is there a setting I can change so that the Quick Input panel  
always uses the most recent item from the clipboard?

Thanks in advance for your help,

Colman
