Howto | mAKE BETTER USE OF KEYBOARD SHORTCUTS
1 Assign shortcuts
Where menu items have no shortcut, you can assign your own. In the Keyboard pane, choose Shortcuts > App Shortcuts and click the + under the right pane. In the form, select the relevant app, type the menu item’s name exactly as shown in the menu (some items include an ellipsis, which is typed with å+;), and hold the shortcut you want to use, ensuring it isn’t already used in that app.
2 Keyboard navigation
You can navigate the menu bar using the keys by pressing ≈+@ (and ƒ on compact keyboards) to put the focus in the menu bar’s left-hand side. Use the arrow keys to move through the menus, and press ® to select an item. Shortcuts for the status icons and the Dock are listed in Keyboard preferences > Shortcuts > Keyboard; not all third-party menu extras can take the focus.
3 Step through forms
Pressing † steps through text boxes and lists in web forms but skips other items. Press ≈+& (and ƒ on small keyboards) to toggle the Full Keyboard Access setting, enabling keyboard navigation to all items. This also works with buttons in dialogs; press † until the one you want has a blue outline (not a blue face, which is the default option, invoked with ® ) then press the spacebar.
