The shortcuts that are displayed in red color are associated with several functions. To find a keyboard shortcut in the list, enter a function name or shortcut in the Filter field. To view all functions available in Qt Creator and the keyboard shortcuts defined for them, select Tools > Options > Environment > Keyboard. For example, selecting and deleting words or lines in an editor. In addition, you can specify your own keyboard shortcuts for some functions that can be easily performed with a mouse, and therefore do not appear in menus or have default keyboard shortcuts.
You can add more shortcuts if your favorite combination is missing. Qt Creator provides various keyboard shortcuts to speed up your development process.
