About MasterKey — Google Sheets shortcuts for the actions you use most

In Google Sheets, MasterKey shows the shortcuts for what you keep doing with the mouse, most-used first, in the corner of your sheet. Nothing pops up to interrupt you. ■ Starts with what you still do by mouse Which shortcuts are worth learning depends on you. Someone who filters every day and someone who formats every day need different ones. MasterKey counts what you do and shows the ones you reach for with the mouse most. ■ Learn it and it goes, then the next one arrives Use a shortcut ten times on the keyboard and it disappears. Reach for the mouse and it steps back one. When one goes, the next one worth learning moves in on its own. You never have to add anything. - You can always see how many uses are left - With three left the keys are hidden. Hover to reveal them ■ Or choose for yourself Want to learn something first? Swap it in from the side panel. When an action has more than one shortcut, pick the one you want to learn. ■ Side panel Browse all 200+ Google Sheets shortcuts. See how many you have learned and what you still do with the mouse. ■ Privacy - Your data never leaves your device. Cell contents and personal information are never sent - Anonymous usage stats (counts only) are sent by default to improve the product. You can turn this off in settings at any time ■ Getting started 1. Install it and open Google Sheets 2. Work the way you always do 3. Within a few days your own list is ready Open the side panel from the M icon in the toolbar, or from "MasterKey" in the corner of your sheet.
