CtrlCmdPageUpPageDown

CtrlCmdPageUpPageDown refers to a family of keyboard shortcuts that combine the control modifier (Ctrl on Windows and Linux, Cmd on macOS) with the Page Up and Page Down keys to navigate within software applications. The exact effect depends on the program and platform, but the common purpose is to move through content, pages, tabs, or sections quickly without using the mouse.

In Windows and Linux environments, typical mappings include:

- Switching between tabs in web browsers and many text editors (previous tab with Page Up, next tab with Page Down) when accompanied by Ctrl.

- Moving between worksheets in spreadsheet programs such as Microsoft Excel (Ctrl+Page Up moves to the previous worksheet, Ctrl+Page Down to the next).

- Navigating pages in document editors like Microsoft Word (Ctrl+Page Up goes to the previous page, Ctrl+Page Down to the next page).

On macOS, the same idea is often accessed with the Cmd modifier, though the availability and exact behavior depend on the application. Some macOS apps map Cmd+Page Up/Down to similar navigation, while others may use different shortcuts or require Fn to generate Page Up/Down events on keyboards without dedicated keys.

Practical notes:

- Page Up and Page Down keys are sometimes accessed via Fn on compact laptops.

- Not all applications support Ctrl+Page Up/Down on all platforms; many allow customization or remapping of shortcuts.

- When teaching or documenting these shortcuts, it is important to specify the exact program, as behaviors can vary widely between editors, browsers, and office suites.
