I have exactly the same question....except that I COULD use the arrows to move the images in creating my Book Wright book for the first half of the book and then suddenly it wouldn't work anymore.  When it worked, it worked when I double clicked in the image container.  Then~ nothing.  HELP!!!!!!

Yes, I want to do the same thing.

You're able to move containers with the keyboard in Bookwright. Just use the keyboard arrows! 

Moving containers with the arrow keys ONLY works for EMPTY containers. Once you have an image in the container, you can no longer move the container with the arrow keys.

I tested this by doing the following:

1. add new empty image container --> can use arrow keys to move container.

2. add photo in that image container --> can no longer use arrow keys to move container.

3. delete image from image container --> can use arrow keys to move container

Arrow keys NEVER work for text containers.

Test in previous comment done with the following version of BookWright (on Mac)

Version: 1.1.148

Hi Annette - Thanks for your feedback. If you select the container by clicking on the corner of a container you should be able to move it with the keyboard arrows. This works for both empty containers as well as containers with images and text. Just make sure to not click in the middle of the image/container since it won't work in that case. 

Veronica - You are correct of course - it's a matter of where you click ... Corners, corners, corners ;-)  Thanks for letting me know.
