Master Mac keyboard shortcuts
When you see a shortcut like ç+å+C, hold all but the last key, then press that one. ç is the Command key, which is also labelled cmd. å means the Option key, labelled alt or opt.
≈ means the Control key, labelled ctrl, and shown as ^ in shortcuts in the menu bar. ß is the Shift key, which is typically just labelled shift. ∫ means the Delete key, which deletes to the left of the insertion point. Press ƒ+∫ to delete to the right.
† is the Tab key, which shifts the focus between some controls in windows and web forms. Turn on Full Keyboard Access in System Preferences to jump between all controls.
