The web page I found that was not so easy to fill a task. If I want only to put the task name, it's Ok, but is I need to put due dates and other categories, I found myself having to do too much mouse clicks to fill field that should be immediately available to fill.
RTM has a fairly extensive shortcut list - so something like
"Buy Milk ^today 5pm" will schedule it or 5pm today (without the quotes).
Just an fyi
