If you want to delete the last characters by script, why not something like:
delete last char of fld X Or a more complex version might be put the selectedChunk into tWhere put word 2 of tWhere into tStart -- staring char position of the cursor put word 4 of tWhere into tEnd -- ending char position of the cursor if tStart > tEnd then -- just an insertion point delete char tEnd of field X -- delete the character just before the insertion point else -- some field content is selected, so delete char tStart to tEnd of fld X -- delete the selected field content end if I did this from memory, so check the dictionary for the exact expressions returned by the selectedChunk function., On 8/31/2018 1:57 PM, Richmond Mathewson via use-livecode wrote: > Digging further . . . > > I found out that the problem appearas: > > 1.
