The most common use of Add Tabby is to insert a thread after each weft pick to accommodate a tabby pick in designs such as overshot or summer and winter.
When the Add Tabby icon is selected, a screen similar ot the following is presented. The default tabby 1 and 2 treadles are the highest treadles in the tie-up; these treadles can be changed to any other treadles.
When adding Tabby picks, your tie-up may not have the tabby treadles; if that's the case, add the two tabby treadles so that they can be selected. Additional treadles may be added in Project Information | Project Shafts and Treadles.
In the following screenshot, tabby treades have been added as treadles 5 and 6. When Add Tabby is selected, the system defaults to the last two treadles 5 and 6.
When "OK" is clicked, the tabby treadles are alternated and added between each of the existing weft picks. The color used for these new tabby picks will be the current palette color.
Tabby picks can be removed with the Remove Tabby option. By default, the start will be at 2 and will extend through the last weft pick. If you had added teh tabby picks using the before option, you likely would want to start at pick 1, not 2.
Also note the interval. If you've used Add Tabby, the interval should be 2. The 3 is shown when a tie down interval of 3 is to be removed. For example, tie-downs can with an interval of 3 may be added using interleave in Weft Transformation Options.
After clicking Remove Tabby above, the draft looks as follows. The additional unused can be removed, if desired, in Project Settings.
