Keyword add/remove performance

Question

I've been a huge critic of Aperture and with good reason, but once you start using Aperture 1.1 it's hard to go back to iPhoto.
Managing keywords is all messed up but once you figure out how to remove a keyword from a bunch of images, it becomes possible to organize your photos the way you'd like. And the hierarchical keywords are a good idea I think.
But the performance! Ha! It takes about a minute to remove a keyword from 100 photos. Why? I assume it's because for each image it has to write a plist file, usually around 15kB-18Kb in size, and then it fsync's the data. That means the computer stops while the OS writes the data to the disk. There's also a ton of other stuff going on but I don't see those operations stopping and waiting for data to be stored on the disk, so they are probably not slowing things down too much.
I assume this is done to keep the data completely consistent, even in the face of a system or application crash. Nevertheless, it's not really possible to write an application this way and have it perform at all reasonably. There are other ways to guarantee data consistency or at least to enable recovery if the system/app crashes unexpectedly. I'd be happy to make a few suggestions

How to add / remove keybindings from a KeyMap?
Action breakAction = new myAction();
Keymap map = pane.getKeymap();
KeyStroke key = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
map.removeKeyStrokeBinding(key);
map.addActionForKeyStroke(key, breakAction);
I tried to remove the keybinding of the Enter-key from
a textPane.
The textPane is connected to a HTMLDocument. Everytime
I press Enter, a new paragraph is started. This is
very irritating! I don't want to start a new
paragraph, I just want to go down one line. The
strange thing is: when I remove the Enter key from the
keymap of the textPane, the <p> tag is left out. So no
new paragraph is initiated. But all other textformat
tags like <b> and <i> are closed when the Enter key is
pressed. Once again: this is very irritating!
I don't want to loose the textformat when I press
Enter. I just want to go down one line! Is it
possible?I believe you have to get the attribute set of the text on the current line and reapply the attributes to the newline....I agree, it is irritating, but you get used to it if you use the EditorPanes and EditorKits often.
I will show you how to apply the breakAction in your other post.
