Fine Positioning of Text Box?

Folks,

I am extremely inexperienced with Libre Writer, so I must be doing something wrong.

I created a new Avery Template from the Libre Writer templates that are included with Libre. It consists of two frames. I inserted two text boxes, one in each frame. Each text box takes up half of a frame. I then copied each of the text boxes to the other half of each frame (they are table tents, so I need to use a text box so I can make one side of the test upside down and backwards [i.e., rotated 180 degrees]). Didn’t have any problem doing the copy and rotation. I also could easily move the (2nd) textbox in each frame to near the position I wanted by using the arrow keys. But, to fit it precisely into its place, I need to be able to use the Alt-arrow feature. The first one worked fine. But, the second (and ALL SUBSEQUENT ATTEMPTS) fails. When I use the ALT-arrow keys, both the textbox and the frame move together. The arrow keys by themselves still move the textbox independently of the frame, but the fine moves (with the ALT-arrow) move everything together.

How can I get independent movement of textbox, with respect to the frame, with the ALT-Arrow keys.

Thank you.

Regards,

DG
