Aperture 3.x: An Overview of the Keyword Controls in the Control Bar
One way to apply and remove keywords is to use the keyword controls located in the control bar. You can add new keywords to photos or apply preset keywords that are part of a keyword group.
The keyword controls are located at the left side of the control bar, but they are not shown by default.
To show the keyword controls in the control bar
Choose Window > Show Keyword Controls (or press Shift-D).
The following keyword controls appear:
Keyword buttons: These buttons display the preset keywords in the selected keyword preset group. The first eight keywords are assigned to the keyboard shortcut key combination of Option and a number key (1 through 8) on the keyboard. Press Option and a number key on the keyboard (not the numeric keypad) to add the preset keyword to a selected photo, or click a keyword button. The control bar can hold up to 20 keyword buttons. To remove a keyword applied by clicking a button, press Shift-Option and the button’s corresponding number key. To remove all keywords, press Shift-Option-9.
Add Keyword field: Type a new keyword in this field and press Return to add it to a selected photo. If the keyword has been used before, Aperture automatically completes the word as you type it. If the Keywords HUD is locked, you are asked whether you want to unlock the Keywords HUD and add the keyword to the keyword library, or not add the keyword to the photo. To remove a keyword you’ve just applied, type the keyword again and press Shift-Return. Keywords removed using the keyword field are not removed from the Keywords HUD.
Keyword Preset Group pop-up menu: Use this pop-up menu to choose the keyword preset group you want displayed. You can also use the Comma (,) key and Period (.) key to quickly cycle forward and backward through the keyword preset groups. The first eight keywords in the group are assigned to the keyboard shortcut key combination of Option and a number key from 1 through 8.
