People switching from Excel often search for an "add-in for Google Sheets." Google has two kinds of tools, and for keyboard shortcuts the difference matters.
| Google Workspace add-on | Chrome extension | |
|---|---|---|
| Where you get it | Workspace Marketplace (Extensions → Add-ons) | Chrome Web Store |
| Where it runs | Inside the file, in a menu or sidebar | In your browser, on the Sheets page |
| Works in any browser | Yes | Chrome and most Chromium browsers |
| Can catch keystrokes like Alt, E, S, V | Not really | Yes |
| Typical permissions | Access to the spreadsheet via Google APIs | Browser permissions on the Sheets site |
