keyboard shortcuts to add task duration, priority, due date etc#4594

enable keyboard shortcuts to quickly (no mouse click needed) add data such as duration, due date, etc, when adding tasks (see gif below for illustration)

e.g.

• sets scheduled date
  ] sets due date
  ~ sets duration
• sets priority

so i can type:

test task +[opens date menu] ~15m [15 min duration] *1 [top priority] etc

this would make it much faster to add tasks, making it more convenient and more likely for users to actually add that info (adhd folks can be impatient), leading to better organized days :)

(amazingmarvin.com implemented this pretty well, btw, maybe have a look there for inspiration, or maybe you guys could even work together?)
