Just remembered that one can "adjust" a photo frame or text box size a little on a page with the following key combinations:
Command + Option +⬆arrow: increase frame height.
Command + Option +⬇arrow: decrease frame height.
Command + Option + ➜ arrow: increase frame width.
Command + Option + ⬅ arrow: decrease frame width.
To adjust its position on the page use these key combinations:
Command + Control + ➜ arrow: move frame to right.
Command + Control + ⬅ arrow: move frame to left.
Command + Control + ⬆ arrow: rotate frame counter clockwise.
Command + Control + ⬇ arrow: rotate frame clockwise.
You can conver the standard frame (on the left) to this one (on the right)
