How to prevent mergefields from being edited

1. offizieller Beitrag

    Hello,

    I created mergefields in the rtf editor. And set ShowFields to true. My fields are boxed now, and that is what we wish. But when I use the arrow keys to walk through the text, the cursor also visits the 'embeded' text that is in the mergefield (and also the field starter and the field closer). But I want to see them as one character.

    How to do this? So when I use arrows to walk through te text the cursor behaves like the mergefields are only one character?

    Thanks,
    Koob
