Never Lose Your Place When Interrupted: Working Memory and the Mac

Someone says your name. You answer. Thirty seconds later you're back at your desk — and the thing you were doing is gone. Not paused. Gone. And the hunt for the thread takes longer than the interruption itself.

What an interruption actually destroys

When you're mid-task, your brain is holding invisible state: the specific window you were in, the tab, the half-formed thought about what to type next, the three context clues that got you there. None of it is written down. It lives in working memory.

Working memory is volatile. One conversation, one Slack ping, one question from across the room — and the whole stack collapses. You can see the window you were in, but the thread that made sense of it has evaporated. You're not picking up where you left off; you're re-running a search that took ten minutes the first time.

Why ADHD makes this especially costly

Working memory is the cognitive function that ADHD affects most directly. It's not about intelligence or effort — the mental scratchpad where context lives is smaller and clears faster. An interruption that a neurotypical brain recovers from in twenty seconds can cost an ADHD brain fifteen minutes of re-loading.

The compounding problem: the longer the re-load takes, the more likely you'll hit another interruption before you finish it. Two context-wipes in a row and the original task feels genuinely unreachable — so you do something else instead, and the open loop runs until end of day.

Waypoint: one hotkey saves the whole context stack

Waypoint is a Mac app built for exactly this moment. When you feel an interruption coming — someone walks over, a call drops in — you press one hotkey. Waypoint snapshots the app you were in, the tab, and a quick note about your next intended action. That's it: one keystroke, context saved.

When you're back, another keypress restores the snapshot. The app comes forward, you see your note, and you're pointed at the next action. The re-entry that normally takes ten minutes of mental archaeology takes ten seconds of following a signpost.

It's object permanence for your own work. The context doesn't disappear when you look away. It sits in Waypoint, waiting.

Making the save a reflex

The whole habit is one key chord. The friction is small. The payoff is ten minutes saved per interruption, compounded across a day of constant context-switching.

1. Set the Waypoint hotkey to something your non-dominant hand can hit without looking — you'll press it mid-sentence.
2. Add a one-line note to each snapshot. 'About to write the intro' beats 'Safari, google.com' for getting back on track fast.
3. When you return, restore before you do anything else — before Slack, before answering the follow-up question.
4. If the interruption is your own wandering attention rather than an external demand, pair Waypoint with FocusJail to handle both sides.
