A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
I usually don't like using the mouse and I don't think there's a way to set reminders or due dates (issue already exists at #1084 for just the due date but not reminders) without mouse.

Describe the solution you'd like
A clear and concise description of what you want to happen.
It would be great if there was something like Todoist's !tomorrow syntax to set a reminder.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Maybe a keyboard shortcut for reminders.
