If you could have one personal shortcut key — what would it do?

I've been thinking a lot about how many tiny actions we repeat dozens of times a day — typing our email, inserting today's date, pasting something without the formatting, saving a quote we just read.

None of them are hard. But they all pull you out of what you were doing.

A fun question: if you had one dedicated key on your keyboard that did exactly one thing — just for you, nothing else — what would it do?

Could be practical (type your email, open a specific app), could be wild (trigger a dramatic Slack status, send a pre-written passive-aggressive reply), could be deeply specific to your job.
