Linear is built for the keyboard — create issues, navigate, and set status, priority and labels without the mouse.
Linear was designed around the keyboard, so learning its shortcuts has an unusually high payoff. The command menu (⌘K / Ctrl+K) does anything by name, and pressing C creates an issue from anywhere. Navigation uses memorable "G then key" sequences — G then I for inbox, for example — that read like little sentences once you've used them a few times.
Where Linear really shines is editing issues without touching the mouse: A to assign, S for status, P for priority, L for labels, I to assign to yourself. Run through a backlog and you can triage dozens of issues in the time it would take to click through one. Press ? any time inside Linear to pull up the complete, current list. If your team also uses other trackers, compare with the Jira shortcuts.
