Data range navigation. Cmd+Arrow jumps to the last filled cell in the arrow's direction, identical to Excel on Mac and Google Sheets on Mac. For large tables, this makes navigating to the edge of a dataset fast.
Canvas object navigation. Numbers' canvas model means a sheet can contain multiple tables and other elements. Keyboard shortcuts exist for switching focus between tables and other canvas objects on the same sheet. The table above covers these canvas-level navigation controls.
Formula entry. Entering edit mode in a cell, navigating within the formula bar, and accepting or canceling formula entries all have Command-based shortcuts. Numbers' formula system uses the same function names as Excel for most common functions.
Number formatting. Applying format types (number, currency, percentage, date, duration) by keyboard, and opening the Format panel for custom format settings.
Table structure. Adding and removing rows, columns, and header/footer rows in a table; navigating the table headers, all keyboard-accessible.
Sheet navigation. Switching between sheets in a Numbers document by keyboard, and working with multiple sheets.
