Hi Product Hunt 👋 I'm Kuranaka, the maker of MasterKey. I started my career in consulting, living in Excel where keyboard shortcuts were pure muscle memory. Then I joined a startup that runs entirely on Google Workspace — and that muscle memory broke. I caught myself slowly clicking through Sheets toolbars like it was 2005. What surprised me most was how many people never use shortcuts at all — even folks who live in spreadsheets all day. And relearning them from cheat sheets never sticks: you forget them the second you close the list. So I built MasterKey. It does one thing: the moment you click a button in Sheets, it shows you the shortcut you could have pressed instead. You don't study shortcuts — you absorb the ones you actually use, exactly when you use them. (Inspired by IntelliJ's Key Promoter X, which did this for coding.) A few things I cared about: • Privacy — it only sees which button you click, never your data. • Mac & Windows keys, shown side by side. • It's designed to fade out: once a shortcut sticks, you stop needing the nudge. It's free, and I'd genuinely love your feedback — especially on which actions you'd want covered next. I'll be here all day answering everything. Thank you for checking it out 🙏
