2) Go to the HTML tab for the button's settings, give it an ID, and then enter "display: none;" into its Style box. This will prevent it from being seen on the web.
3) Finally, enter the following code into the "onDblClick()" event for your form:
document.getElementById("[your edit button's ID]").click();
(Replace [your edit button's ID] with your edit button's ID, if you were wondering. :P )
That's it! Now, whenever the user doubleclicks anywhere on the document during read mode, they'll be automatically catapulted into edit mode. They're probably already expecting this behavior, so they'll definitely thank you!
Of course, you may notice that this doubleclick behavior happens in edit mode, as well (running @Command([EditDocument]) in edit mode takes the document out of edit mode without saving) -- I like this because its a feature that I believe should be in notes, but isn't. If you want it to stop, just add a condition to the onDblClick() event featuring a variable that captures the document's edit status. It's that simple.
