KeyGuide is a plain-English reference for the keyboard shortcuts office workers actually use. Every shortcut is described by what it does โ€” like "Reopen the tab you just closed" โ€” with the keys shown as easy-to-read keycaps, so you can find the right one even when you don't know what it's called. Browse nine guides organized by program and task, or search by what you're trying to do. When you find a shortcut you want to keep handy, tap the star to add it to your personal Saved list. The guides: โ€ข Excel โ€” 71 shortcuts โ€ข Word โ€” 49 shortcuts โ€ข Outlook โ€” 24 shortcuts โ€ข PowerPoint โ€” 18 shortcuts โ€ข Teams โ€” 12 shortcuts โ€ข Windows โ€” 34 shortcuts โ€ข Web browsers โ€” 22 shortcuts โ€ข Works everywhere โ€” 19 shortcuts that work in almost any program โ€ข Mac basics โ€” 17 shortcuts KeyGuide works fully offline and collects no data at all. There is no account to create and no ads. Your starred shortcuts are stored only on your device. It's a one-time free download โ€” open it whenever you need it. KeyGuide is an independent reference and is not affiliated with or endorsed by Microsoft, Apple, or any browser maker. Program names are used only to identify which shortcuts apply to which software.
