With the mirror function, you can mirror images, graphic objects, and text frames horizontally or vertically to create interesting and creative effects. Regarding a text frame, it should be noted that the text is not mirrored letter by letter; instead, the alignment of the entire frame is adjusted.

How does it work?

1. Select the desired object.
2. Either the graphic floating toolbox will appear, or you should switch to the "Graphics" palette.
3. There, select the icon for horizontal or vertical mirroring.
   

Can I mirror individual letters in a text?

No, unfortunately, that is not possible. Essentially, you are mirroring a text frame.

For header lines, there is a workaround: Take the text frame and convert it to a polygon using the "Text to Path" function. In this case, each letter is a separate polygon and can be manipulated.
Please note that this is not a viable solution for body text. On one hand, because subsequent correction of the text is no longer possible. On the other hand, performance is reduced by such actions.
