I often come across segments that can not (yet) be translated, but I want to mark them as "dealt with". So I wrote a little "filler text generator" using the notorious "Lorem ipsum" (sorry to Signore Cicero!). It will not work on segments with less than 5 characters, so that you always get at least "Lorem", which you can then search for in your target documents.
As published here it will insert "Lorem ipsum" filler text, the length of which (ratio) can be set by the user. No exception handling, so be reasonable with the value you set.
Then the segment status is altered and the segment locked. You can modify as desired.
